[PATCH v2 net-next] be2net: disable bh with spin_lock in be_process_mcc

[Denis Kirjanov]

be_process_mcc() is invoked in 3 different places and
always with BHs disabled except the be_poll function
but since it's invoked from softirq with BHs
disabled it won't hurt.

v1->v2: added explanation to the patch
