The failure to create debugfs entry is unpleasant event, but not enough
to abort drier initialization. Align the mlx5_core code to debugfs design
and continue execution whenever debugfs_create_dir() successes or not.
Fixes: e126ba97dba9 ("mlx5: Add driver for Mellanox Connect-IB adapters")

It goes to -next and not to -rc, because this issue was forever.
