If the current USB request was aborted, the spi thread would not respond
to any further requests. This is because the "curr_urb" pointer would
not become NULL, so no further requests would be taken off the queue.
The solution here is to set the "urb_done" flag, as this will cause the
correct handling of the URB. Also clear interrupts that should only be
expected if an URB is in progress.
