btrfs-progs: Fix an extent buffer leak in qgroups check
Qgroup verify codes will read fs root to check if the subvolume exists. But it forgot to free the extent buffer read out, only freeing the memory. Fix it by also freeing the extent buffers. Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.com>
