RDMA/mlx5: Lock access to ent->available_mrs/limit when doing queue_work

Browse source

Accesses to these members needs to be locked. There is no reason not to
hold a spinlock while calling queue_work(), so move the tests into a
helper and always call it under lock.

The helper should be called when available_mrs is adjusted.
