ceph: check POOL_FLAG_FULL/NEARFULL in addition to OSDMAP_FULL/NEARFULL
CEPH_OSDMAP_FULL/NEARFULL aren't set since mimic, so we need to consult per-pool flags as well. Unfortunately the backwards compatibility here is lacking: - the change that deprecated OSDMAP_FULL/NEARFULL went into mimic, but was guarded by require_osd_release >= RELEASE_LUMINOUS - it was subsequently backported to luminous in v12.2.2, but that makes no difference to clients that only check OSDMAP_FULL/NEARFULL because require_osd_release is not client-facing -- it is for OSDs Since all kernels are affected, the best we can do here is just start checking both map flags and pool flags and send that to stable. These checks are best effort, so take osdc->lock and look up pool flags just once. Remove the FIXME, since filesystem quotas are checked above and RADOS quotas are reflected in POOL_FLAG_FULL: when the pool reaches its quota, both POOL_FLAG_FULL and POOL_FLAG_FULL_QUOTA are set.
