Fix the following compiler warning (found by the kbuild test robot):
drivers/usb/host/ehci-hcd.c:312:13: warning: 'unlink_empty_async_suspended' declared 'static' but never defined
Commit 2a40f324541e ("USB: EHCI: fix regression during bus resume")
protected the function definition with a "#ifdef CONFIG_PM" block, so
now the declaration needs to be similarly protected. This patch moves
it to a better location.
