net/mlx5e: SHAMPO, Release in progress headers

Browse source

The change in the fixes tag cleaned up too much: it removed the part
that was releasing header pages that were posted via UMR but haven't
been acknowledged yet on the ICOSQ.

This patch corrects this omission by setting the bits between pi and ci
to on when shutting down a queue with SHAMPO. To be consistent with the
Striding RQ code, this action is done in mlx5e_free_rx_missing_descs().
