Revert "block: Add a new REQ_PRIO, f2fs quick hack"

This reverts commit 45b5083dd33dd146096441421f74198ead8dba2d.
block: separate priority boosting from REQ_META

Add a new REQ_PRIO to let requests preempt others in the cfq I/O schedule,
and lave REQ_META purely for marking requests as metadata in blktrace.

All existing callers of REQ_META except for XFS are updated to also
set REQ_PRIO for now.
