net/mlx5: Disable eswitch before waiting for VF pages
[ Upstream commit 7ba930fc25def6fd736abcdfa224272948a65cf7 ]
The offending commit changed the ordering of moving to legacy mode and
waiting for the VF pages. Moving to legacy mode is important in
bluefield, because it sends the host driver into error state, and frees
its pages. Without this transition we end up waiting 2 minutes for
pages that aren't coming before carrying on with the unload process.
