cxgb4: use port number to set mac addr
[ Upstream commit 356983f569c1f5991661fc0050aa263792f50616 ] t4_set_vf_mac_acl() uses pf to set mac addr, but t4vf_get_vf_mac_acl() uses port number to get mac addr, this leads to error when an attempt to set MAC address on VF's of PF2 and PF3. This patch fixes the issue by using port number to set mac address.
