Subject: [PATCH 1/2] USB: storage: ums-realtek: Rename module parameter auto_delink_en to auto_delink_mode

The option named "auto_delink_en" is a bit misleading, as setting it to
false doesn't really disable auto-delink but let auto-delink be firmware
controlled.

Rename it to reflect the real usage of this parameter.
