Subject: net/mlx5e: Do not request completion on every single UMR WQE
Patch-mainline: v5.9-rc1
Git-commit: 0bdc89b39d622b8929a687eee194e4e166fe84df
References: jsc#SLE-15172
UMR WQEs are posted in bulks, and HW is notified once per a bulk.
Reduce the number of completions by requesting such only for
the last WQE of the bulk.
