UDL driver uses a semaphore for controlling the emptiness of FIFO in a
slightly funky way. This patch replaces it with a wait queue and
controls the emptiness with the standard wait_event*() macro instead,
which is a more straightforward implementation.
While we are at it, drop the dead code for delayed semaphore down,
too.
