Yishai Hadas be551ee157 RDMA/mlx5: Relax DEVX access upon modify commands
Relax DEVX access upon modify commands to be UVERBS_ACCESS_READ.

The kernel doesn't need to protect what firmware protects, or what
causes no damage to anyone but the user.

As firmware needs to protect itself from parallel access to the same
object, don't block parallel modify/query commands on the same object in
the kernel side.

This change will allow user space application to run parallel updates to
different entries in the same bulk object.
