qemu: use switch instead of if in qemuProcessPrepareDomainNetwork()

Browse Source 
qemuProcessPrepareDomain()'s comments say that it should be the only
place to change the "live XML" of a domain (i.e. the public parts of
the virDomainDef object that is shown in the domain's status
XML), and that seems like a reasonable idea (although there aren't
many users of it to date).

qemuProcessPrepareDomainNetwork() is called by the aforementioned
qemuProcessPrepareDomain() - this patch changes the "if (type ==
HOSTDEV)" in that function to a "switch(type)" so it's simpler to add
DomainDef modifications for various other types of virDomainNetDef,
and also so that anyone who adds a new interface type is forced to
look at the code and decide if anything needs to be done here for the
new type.
