As of commit d8649fc1c5e4 ("scsi: libsas: Do discovery on empty PHY to
update PHY info"), do discovery will send a new SMP_DISCOVER and update
phy->phy_change_count. We found that if the disk is reconnected and phy
change_count changes at this time, the disk scanning process will not be
triggered.
So update the PHY info with the last query results.

v1 -> v2:
Use sas_get_phy_discover() instead of sas_get_phy_attached_dev() in
sas_rediscover_dev() and use disc_resp to update phy info.
