bcachefs: Don't set BCH_FS_error on transaction restart

This started showing up more when we started logging the error being
corrected in the journal - but __bch2_fsck_err() could return
transaction restarts before that.

Setting BCH_FS_error incorrectly causes recovery passes to not be
cleared, among other issues.
