Subject: net/mlx5: Don't rely on always true registered field
Patch-mainline: v5.15-rc1
Git-commit: 35f6986743d78544779a892415c2edefa1f36a1c
References: jsc#SLE-19253

Devlink is an integral part of mlx5 driver and all flows ensure that
devlink_*_register() will success. That makes the ->registered check
an obsolete.
