Kai-Heng,
Actually, I saw that the fix just landed in bionic-proposed in version 4.15.0-46.49 on 2019-02-15, so bionic-updates and bionic-security don't have the fix yet as of today.
Changelog for anyone wanting to know: https://launchpad.net/ubuntu/+source/linux/+changelog
Relevant snippet:
* Bionic update: upstream stable patchset 2019-01-17 (LP: #1812229) - xhci: Fix perceived dead host due to runtime suspend race with event handler
