[ Upstream commit 12f371e2b6cb4b79c788f1f073992e115f4ca918 ]

Function checkdone is only required if QUIRK2 is defined, so add
appropriate #if / #endif around the function.

Cleans up clang scan build warning:
drivers/usb/host/sl811-hcd.c:588:18: warning: unused function
'checkdone' [-Wunused-function]
