blk-mq: Fix timeout handling in case the timeout handler returns BLK_EH_DONE 

Make sure that RQF_TIMED_OUT is cleared when a request is reused
after a block driver timeout handler has returned BLK_EH_DONE.

Fixes: da66126739 ("blk-mq: don't time out requests again that are in the timeout handler")
