block/mq-deadline: Set the fifo_time member also if inserting at head
[ Upstream commit725f22a147
] Before commit322cff70d4
the fifo_time member of requests on a dispatch list was not used. Commit322cff70d4
introduces code that reads the fifo_time member of requests on dispatch lists. Hence this patch that sets the fifo_time member when adding a request to a dispatch list.
