[BUG]
btrfs check can return strange return value for shell:
[Inferior 1 (process 48641) exited with code 0213]
^^^^
[CAUSE]
It's caused by the incorrect handling of qgroup error.
qgroup_report_ret can be -117 (-EUCLEAN), using that value with exit()
can cause overflow, causing return value not properly recognized.
[FIX]
Fix it by sanitize the return value to 0 or 1.
