usb: ehci: mark unlink_empty_async_suspended() as __maybe_unused
Patch 4d053fdac3 "usb: ehci: unlink_empty_async_suspended() only used
with CONFIG_PM" tried to hide the unlink_empty_async_suspended function
inside of an #ifdef to work around an unused function warning.
Unfortunately that had the effect of introducing a new warning:
drivers/usb/host/ehci-q.c:1297:13: warning: 'unlink_empty_async_suspended'
declared 'static' but never defined [-Wunused-function]
While we could add another #ifdef around the function declaration to avoid
this, a nicer solution is to mark it as __maybe_unused, which will let
gcc silently drop the function definition when it is not needed.
