Break out the multicast programming into its own hardware specific
call, which assumes the hardware is awake.

Turn ath_update_mcast() into a routine that's only called from the
net80211 layer - and it forces the hardware awake first.

This fixes a LOR from the EDMA RX path which calls ath_mode_init()
with the RX lock held - the driver lock can't also be grabbed.
This path assumes that the ath_mode_init() callers all wake up
the NIC first.

Tested:

* AR9485, STA mode, powersave
