IB/mlx5: Fix post send fence logic
commit c9b254955b9f8814966f5dabd34c39d0e0a2b437 upstream.
If the caller specified IB_SEND_FENCE in the send flags of the work
request and no previous work request stated that the successive one
should be fenced, the work request would be executed without a fence.
This could result in RDMA read or atomic operations failure due to a MR
being invalidated. Fix this by adding the mlx5 enumeration for fencing
RDMA/atomic operations and fix the logic to apply this.
Fixes: e126ba97dba9 ('mlx5: Add driver for Mellanox Connect-IB adapters')
