[libvirt] [PATCH v2 10/39] qemuDomainGetHostdevPath: Use more VIR_AUTOFREE/VIR_AUTOPTR

[Michal Privoznik]

There are several variables which could be automatically freed
upon return from the function. I'm not changing @tmpPaths (which
is a string list) because it is going to be removed in next
commit.
