[SRU] [Bionic] [OEM-B] [PATCH 0/2] Fix "xhci_hcd 0000:00:14.0: Root hub is not suspended"

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1779823

[Impact]
Runtime suspended xHC keeps spewing out this message:
xhci_hcd 0000:00:14.0: Root hub is not suspended

[Test]
With the fix, the message stops.

[Fix]
Only decrement PM counter when DBC was started.

[Regression Potential]
Low. It fixes the overlooked logic.
