Firstly, bring variables that are used only within loops into
their respective loops. Secondly, drop 'error' label which is
redundant since we have @rv which holds the return value.
Thirdly, fix indendation in one case, the rest is indented
properly.

We don't need to track the lease file size. Instead, we can
simply check if the file was empty by comparing the buffer the
file was read into with an empty string.

When adding a new lease by our leaseshelper then virLeaseNew() is
called. Here, we check for DNSMASQ_LEASE_EXPIRES environment
variable which is the expiration time for the lease. For infinite
lease time the value is zero. However, our code is not prepared
for that and adds "expiry-time" into the JSON file only if lease
expiry time is non-zero. This breaks the assumption that the
"expiry-time" attribute is always present (as can be seen in
virLeaseReadCustomLeaseFile() and virLeasePrintLeases()).
Store "expiry-time" always.

In virLeaseNew() we are trying to remove trailing space (per
comment it may happen that older versions of dnsmasq put it into
an env variable). Well, instead of open coding it, we can use
virTrimSpaces().

If leasehelper fails all that we are left with is a simple error
message produced by dnsmasq:
lease-init script returned exit code 1
This is because the leasehelper did not write any message to
stderr. According to dnsmasq's manpage, whenever it's invoking
leasehelper the stderr is kept open:
All file descriptors are closed except stdin, which is open to
/dev/null, and stdout and stderr which capture output for
logging by dnsmasq.
As debugging leasehelper is not trivial (because dnsmasq invokes
it with plenty of env vars set - that's how data is passed onto
helper), let's print an error into stderr if exiting with an
error. And since we are not calling public APIs, we have to call
virDispatchError() explicitly and since we don't have any
connection open, we have to pass NULL.

In recent patches new mambers to _qemuAgentDiskAddress struct
were introduced to keep optional CCW address sent by the guest
agent. These two members are a struct to store CCW address into
and a boolean to keep track whether the CCW address is valid.
Well, we can hold the same information with a pointer - instead
of storing the CCW address structure let's keep just a pointer to
it.

On s390x, devices are attached to the channel IO subsytem by default,
so we need to look up scsi controllers via their CCW address there
instead of using PCI.
This fixes "virsh domfsinfo" on s390x for virtio-scsi devices (the first
attempt from commit f8333b3b0a did it in the wrong way, reporting the
