On mount failures, __btrfs_close_devices can be called well before dev-replace state is read and ->is_tgtdev_for_dev_replace is set. This leads to a bogus decrement of ->rw_devices and sets off a WARN_ON in __btrfs_close_devices if replace target device happens to be on the lists and we fail early in the mount sequence. Fix this by checking the devid instead of ->is_tgtdev_for_dev_replace before the decrement: for replace targets devid is always equal to BTRFS_DEV_REPLACE_DEVID.
