RDMA/mlx5: Change check for cacheable mkeys
[ Upstream commit 8c1185fef68cc603b954fece2a434c9f851d6a86 ]
umem can be NULL for user application mkeys in some cases. Therefore
umem can't be used for checking if the mkey is cacheable and it is
changed for checking a flag that indicates it. Also make sure that
all mkeys which are not returned to the cache will be destroyed.
Fixes: dd1b913fb0d0 ("RDMA/mlx5: Cache all user cacheable mkeys on dereg MR flow")
