bnx2i: Fix call trace while device reset
The driver waits for command completion event while cleanup of task within the frwd lock and back locks. The frwd lock was still held which caused the call trace while issuing a device reset. Release the frwd lock along with the back lock to avoid waiting in the lock context.
