[PATCH 13/17] usb: xhci: remove redundant function wrapper

From: Niklas Neronin <[email protected]>

The function ring_doorbell_for_active_rings() rings the doorbell
for any rings with pending URBs. It has a trivial wrapper,
xhci_ring_doorbell_for_active_rings(), which takes the same
arguments and simply calls the former.

Since the wrapper adds no functionality, remove it and rename
ring_doorbell_for_active_rings() to xhci_ring_doorbell_for_active_rings().
