Now that virPCIDeviceIsPCIExpress() checks the length of the file when
the process lacks sufficient privilege to read the entire PCI config
file in sysfs, we can remove the open-coding for that case from its
consumer.

Until now there has been an extra bit of code in
qemuDomainDeviceCalculatePCIConnectFlag() (one of the two callers of
virPCIDeviceIsPCIExpress()) that tries to determine if a device is
PCIe by looking at the *length* of its sysfs config file; it only does
this when libvirt is running as a non-root process.
This patch takes advantage of our newfound ability to tell the
difference between "I read a 0 from the device PCI config file" and "I
couldn't read the PCI Express Capabilities because I don't have
sufficient permission" to put the file length check down in
virPCIDeviceIsPCIExpress(), and do that check any time we fail while
reading the config file (not only when the process is non-root).

Previously there was no way to differentiate between this function 1)
encountering an error while reading the pci config, and 2) determining
that the device in question is a conventional PCI device, and so has
no Express Capabilities.
The difference between these two conditions is important, because an
unprivileged libvirtd will be unable to read all of the pci config (it
can only read the first 64 bytes, and will get ENOENT when it tries to
seek past that limit) even though the device is in fact a PCIe device.
This patch changes virPCIDeviceFindCapabilityOffset() to put the
determined offset into an argument of the function (rather than
sending it back as the return value), and to return the standard "0 on
success, -1 on failure". Failure is determined by checking the value
of errno after each attemptd read of the config file (which can only
work reliably if errno is reset to 0 before each read, and after
virPCIDeviceFindCapabilityOffset() has finished examining it).
(NB: if the config file is read successfully, but no Express
Capabilities are found, then the function returns success, but the
returned offset will be 0 (which is an impossible offset for Express
Capabilities, and so easily recognizeable).
An upcoming patch will take advantage of the change made here.
