qlcnic: Fix multicast packet handling for PF and VF. 



o Multicast MAC was not getting programmed due to which multicast
  packets were being dropped by FW.

This patch fixes commit 168e4fb54c11865668ad50eff81b5f2729e0e0f4
("qlcnic: Secondary unicast MAC address support.") which introduced
bug in handling multicast packets.
