libceph: don't set flags in ceph_osdc_alloc_request()
The only thing ceph_osdc_alloc_request() really does with the flags value it is passed is assign it to the newly-created osd request structure. Do that in the caller instead. Both callers subsequently call ceph_osdc_build_request(), so have that function (instead of ceph_osdc_alloc_request()) issue a warning if a request comes through with neither the read nor write flags set.
