hd: dequeue and track in-flight request
hd has at most single request in flight. Till now, whenever it needs
to access the in-flight request it called elv_next_request(). This
patch makes hd track the in-flight request directly and dequeue it
when processing starts. The added complexity is minimal and this will
help future block layer changes.
[ Impact: dequeue in-flight request, one elv_next_request() per request ]
