9b7d4be967 RDMA/mlx5: Fix UMR cleanup on error flow of driver init 
The cited commit removed from the cleanup flow of umr the checks
if the resources were created. This could lead to null-ptr-deref
in case that we had failure in mlx5_ib_stage_ib_reg_init stage.

Fix it by adding new state to the umr that can say if the resources
were created or not and check it in the umr cleanup flow before
destroying the resources.

158e71bb69 RDMA/mlx5: Add a umr recovery flow 
When a UMR fails, the UMR QP state changes to an error state. Therefore,
all the further UMR operations will fail too.

Add a recovery flow to the UMR QP, and repost the flushed WQEs.

Move mlx5_ib_update_mr_pas logic to umr.c, and use

Since it is the last use of mlx5_ib_post_send_wait(), remove it.

6f0689fdf1 RDMA/mlx5: Introduce mlx5_umr_post_send_wait() 
Introduce mlx5_umr_post_send_wait() that uses a UMR adjusted flow for
posting WQEs. The next patches will gradually move UMR operations to use
this flow. Once done, will get rid of mlx5_ib_post_send_wait().

mlx5_umr_post_send_wait gets already written WQE segments and will only
memcpy it to the SQ. This way, we avoid packing all the data in a WR just
to unpack it into the WQE.
