libceph: allow ceph_osdc_new_request to accept a multi-op read

Currently we have some special-casing for multi-op writes, but in the
case of a read, we can't really handle it. All of the current multi-op
callers call it with CEPH_OSD_FLAG_WRITE set.

Have ceph_osdc_new_request check for CEPH_OSD_FLAG_READ and if it's set,
allocate multiple reply ops instead of multiple request ops. If neither
flag is set, return -EINVAL.
