__ceph_caps_mds_wanted() ignores caps from stale session. So the return value of __ceph_caps_mds_wanted() can keep the same across ceph_renew_caps(). This causes try_get_cap_refs() to keep calling ceph_renew_caps(). The fix is ignore the session valid check for the try_get_cap_refs() case. If session is stale, just let the caps requester sleep.
