net/mlx5: Continue driver initialization despite debugfs failure

Browse Source 
[ Upstream commit 199fa087dc6b503baad06712716fac645a983e8a ]

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.
