dm: remove unused flush_all

This patch removes the DM_WQ_FLUSH_ALL state that is unnecessary.

The dm_queue_flush(md, DM_WQ_FLUSH_ALL, NULL) in dm_suspend()
is never invoked because:
  - 'goto flush_and_out' is the same as 'goto out' because
    the 'goto flush_and_out' is called only when '!noflush'
  - If r is non-zero, then the code above will invoke 'goto out'
    and skip this code.

No functional change.
