IB/mlx4: Fix potential deadlock when sending mad to wire

Browse source

commit 90c1d8b635 upstream.

send_mad_to_wire takes the same spinlock that is taken in
the interrupt context.  Therefore, it needs irqsave/restore.

Fixes: b9c5d6a643 ('IB/mlx4: Add multicast group (MCG) paravirtualization for SR-IOV')
