usb: rename usb_drv_recv() to usb_recv_recv_nonblocking()

IMHO the current name is somewhat misleading:

- usb_drv_send() is blocking and we have usb_drv_send_nonblocking()
  for the non-blocking case. This inconsistent naming can only
  promote confusion. (And what would we call a blocking receive?)

- Other hardware abstraction APIs in Rockbox are usually blocking:
  storage, LCD, backlight, audio... in other words, blocking is the
  default expected behavior, with non-blocking calls being a rarity.
