ixgbevf: fix MAC address changes through ixgbevf_set_mac()

Browse Source 
[ Upstream commit 6e7d0ba1e59b1a306761a731e67634c0f2efea2a ]

Set hw->mac.perm_addr in ixgbevf_set_mac() in order to avoid losing the
custom MAC on reset. This can happen in the following case:

>ip link set $vf address $mac
>ethtool -r $vf
