net/mlx5e: Disable TX MPWQE in kdump mode
Under kdump environment we want to use the smallest possible amount
of resources, that includes setting SQ size to minimum.
However, when running on a device that supports TX MPWQE, then the SQ stop
room becomes larger than with non-capable device and requires increasing
the SQ size.
Since TX MPWQE offload is not necessary in kdump mode, disable it to
reduce the memory requirements for capable devices.
With this change, the needed SQ stop room size drops by 31.
