UPSTREAM: block/mq-deadline: Set the fifo_time member also if inserting at head

Before commit 322cff70 the fifo_time member of requests on a dispatch
list was not used. Commit 322cff70 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.
