Subject: [PATCH] util: eliminate useless local variable
vf in virNetDevMacVLanDeleteWithVPortProfile() is initialized to -1
and never set. It's not set for a good reason - because it doesn't
make sense during macvtap device setup to refer to a VF device as
"PF:VF#". This patch replaces the two uses of "vf" with "-1", and
removes the local variable, so that it's more clear we are always
calling the utility functions with vf set to -1.
Resolves: https://bugzilla.redhat.com/1442040 (RHEL 7.3.z)
Resolves: https://bugzilla.redhat.com/1415609 (RHEL 7.4)
(cherry picked from commit 606a01339563b5371f21a9b2c10ef818c0557fb1)
