[libvirt] [PATCH] Move virGetUserEnt() to where its needed

[Doug Goldstein]

In the first if case, virGetUserEnt() isn't necessary so don't bother
calling it before determining we need it.

Found this trying to get libvirtd running happily on my Mac OS X machine
for qemu. Unfortunately it appears virGetUserEnt() is always failing
on Mac OS X (getpwuid_r() returns 0 each time) because we are requesting
info on a different high value UIDs each time (32xxx). That's another
issue entirely but this fix allows me to ignore that and test other
fixes on my Mac.
