  Log:
  Remove all remaining support for LK_DRAIN lockmgr locks.  LK_DRAIN was a
  mechanism that allowed lock requests to fail while a thread is blocked
  disposing of a structure that has not been entirely unlinked from the
  rest of the system, but LK_DRAIN's design only works on UP systems or
  while the BGL is held.  It cannot be used in concurrent environments.
  Just get rid of it entirely.
