be2net: Use MCC queue for cmds that may be called in BH context
Currenlty multicast_set and promiscuous_config cmds -- that may be called in BH context --
use the blocking MCC mbox to post cmds.
An mbox cmd is protected via a spin_lock(cmd_lock) and not spin_lock_bh() as it is undesirable
to disable BHs while a blocking mbox cmd is in progress (and take long to finish.)
This can lockup a cmd in progress in process context.
So, these two cmds in BH context must use the MCC queue to post cmds.
