Not sure why any driver needs to sleep for *two* ticks, so let's fix it.

Use msleep() instead of schedule_timeout() to guarantee the
task delays as expected. Signals are never checked for by the callers or
in the function itself, so use TASK_UNINTERRUPTIBLE instead of
TASK_INTERRUPTIBLE. The delay is presumed to have been written when HZ==100,
and thus has been multiplied by 10 to pass to msleep().
