Subject: [PATCH] libsas: continue revalidation

commit 26f2f199ff150d8876b2641c41e60d1c92d2fb81 upstream.

Continue running revalidation until no more broadcast devices are
discovered.  Fixes cases where re-discovery completes too early in a
domain with multiple expanders with pending re-discovery events.
Servicing BCNs can get backed up behind error recovery.
