RDMA/cma: Simplify locking needed for serialization of callbacks
The RDMA CM has some logic in place to make sure that callbacks on a given CM ID are delivered to the consumer in a serialized manner. Specifically it has code to protect against a device removal racing with a running callback function. This patch simplifies this logic by using a mutex per ID instead of a wait queue and atomic variable. This means that cma_disable_remove() now is more properly named to cma_disable_callback(), and cma_enable_remove() can now be removed because it just would become a trivial wrapper around mutex_unlock().
