- Remove asleep(), await(), and M_ASLEEP.

Browse Source 
- Callers of asleep() and await() have been converted to calling tsleep().
  The only caller outside of M_ASLEEP was the ata driver, which called both
  asleep() and await() with spl-raised, so there was no need for the
  asleep() and await() pair.  M_ASLEEP was unused.
