block/mq-deadline: Set the fifo_time member also if inserting at head
Before commit 322cff70d46c the fifo_time member of requests on a dispatch
list was not used. Commit 322cff70d46c 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.
