[libvirt] [PATCH v2 4/4] util: Fixing invalid error checking from virPCIGetNetname()



linkdev is In/Out function parameter as second order reference pointer
so requires first order dereference for checking NULLs which can be a
result from virPCIGetNetName()

Fixes: d6ee56d7237 (util: change virPCIGetNetName() to not return error if device has no net name)
