GFS2: Fix up REQ flags
Christoph has split up REQ_PRIO from REQ_META. That means that we can drop REQ_PRIO from places where is it not needed. I'm not at all sure that the combination WRITE_FLUSH_FUA | REQ_PRIO makes any kind of sense, anyway. In addition, I've added REQ_META to one place in the code where it was missing. REQ_PRIO has been left for read/writes triggered by glock acquisition and writeback only. We can adjust it again if required, but these are the most important points from a performance perspective.
