virnetdev: Use VIR_WITH_MUTEX_LOCK_GUARD in virNetDevGenerateName()
The virNetDevGenerateName() function uses a global array of
virNetDevGenName structs to find next unused name for network
device. This obviously needs some locking and in fact each member
of the array has its own lock. However, these members are not
virObjects, they are just plain structs, therefore
VIR_WITH_MUTEX_LOCK_GUARD() must be used instead of
VIR_WITH_OBJECT_LOCK_GUARD() to lock individual mutexes.
