Revert "be2net: disable bh with spin_lock in be_process_mcc"

Patch was based on wrong presumption that be_poll can be called only
from bh context. It reintroducing old regression (also reverted) and
causing deadlock when we use netconsole with benet in bonding.

Old revert: commit 072a9c486004 ("netpoll: revert 6bdb7fe3104 and fix
be_poll() instead")
