xhci: decouple usb2 port resume and get_port_status request handling

[ Upstream commit b0425784

 ]

The get port status hub request code in xhci-hub.c will complete usb2
port resume signalling if signalling has been going on for long enough.

The code that completes the resume signalling, and the code that returns
the port status have gotten too intertwined, so separate them a bit.
