bcachefs: btree read retry fixes
Fix btree node read retries after validate errors:
__btree_err() is the wrong place to flag a topology error: that is done
by btree_lost_data().
Additionally, some calls to bch2_bkey_pick_read_device() were not
updated in the 6.16 rework for improved log messages; we were failing to
signal that we still had a retry.
