paride: dequeue in-flight request
pd/pf/pcd have track in-flight request by pd/pf/pcd_req. They can be
converted to dequeueing model by updating fetching and completion
paths. Convert them.
Note that removal of elv_next_request() call from pf_next_buf()
doesn't make any functional difference. The path is traveled only
during partial completion of a request and elv_next_request() call
must return the same request anyway.
