[PATCH rdma-next 01/10] RDMA/mlx5: Remove DCT restrack tracking

[Edward Srouji]

From: Patrisious Haddad <phaddad@xxxxxxxxxx>

DCT restrack tracking wasn't working to begin with as it was only
tracking the first DCT which was added, since at creation the DCT number
isn't yet initialized because the DCT FW object is only created during
modify. The following DCT additions were failing silently.
Remove DCT tracking so a later patch which WARNS about restrack addition
failures doesn't WARN about it.

Fixes: fd3af5e21866 ("RDMA/mlx5: Track DCT, DCI and REG_UMR QPs as diver_detail resources.")
