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.
Therefore, call sas_set_ex_phy() to update the PHY info with the
results of
the last query. And because the previous phy info will be used when
calling
sas_unregister_devs_sas_addr(), sas_unregister_devs_sas_addr() should be
called before sas_set_ex_phy().

I am also ok with a change to revert to allocating the resp memory with
alloc_smp_resp(), but make the changes neat please:
