[SRU] [B/D/E/Unstable] [PATCH 0/2] Fix auto-delink on new ums-realtek devices

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1838886

[Impact]
Some ums-realtek card readers may dropped from USB bus after using
ums-realtek driver instead of usb-storage generic driver.

[Fix]
Disable auto-delink on new ums-realtek devices, only whitelist three
oldest IDs.

[Test]
Affected user and myself confirmed disabling auto-delink works.

[Regression Potential]
Minimal. Limited to one specific driver and this also restore the old
behavior.
