Align locking usage when touching device address with rest
of the kernel. Lock the bottom half when doing so using
netif_addr_lock_bh.
This also solves the following case as reported by lockdep:
CPU0 CPU1
---- ----
lock(_xmit_INFINIBAND);
local_irq_disable();
lock(&(&mc->mca_lock)->rlock);
lock(_xmit_INFINIBAND);
<Interrupt>
lock(&(&mc->mca_lock)->rlock);
*** DEADLOCK ***
