treewide: Rename enum req_opf into enum req_op
The type name enum req_opf is misleading since it suggests that values of
this type include both an operation type and flags. Since values of this
type represent an operation only, change the type name into enum req_op.
Convert the enum req_op documentation into kernel-doc format. Move a few
definitions such that the enum req_op documentation occurs just above
the enum req_op definition.
The name "req_opf" was introduced by commit ef295ecf090d ("block: better op
and flags encoding").
