gianfar: Revive VLAN support
commit 77ecaf2d5a8bfd548eed3f05c1c2e6573d5de4ba ("gianfar: Fix VLAN
HW feature related frame/buffer size calculation") wrongly removed
priv->vlgrp assignment, and now priv->vlgrp is always NULL.
This patch fixes the issue, plus fixes following sparse warning
introduced by the same commit:
gianfar.c:1406:13: warning: context imbalance in 'gfar_vlan_rx_register' - wrong count at exit
gfar_vlan_rx_register() checks for "if (old_grp == grp)" and tries
to return w/o dropping the lock.
According to net/8021q/vlan.c VLAN core issues rx_register() callback:
1. In register_vlan_dev() only on a newly created group;
2. In unregister_vlan_dev() only if the group becomes empty.
Thus the check in the gianfar driver isn't needed.
