btrfs-progs: check: verify qgroups above level 0
This commit introduced a new regression which corrupts
read_qgroup_status, since it iterate leaf with manually specified slot,
not correct path->slot[0].
This leads to wrong slot[0] and read_qgroup_status() will read out wrong
flags, leading to regression.
Fix read_qgroup_status() by using eb and slot instread of wrong path
strucutre.

I'm adding this patch to devel. Do you have a test for the regression please?
Xfstests btrfs/114 can produce it.
If you mean to add btrfs-progs test case, then I can try to create a
minimal image to reproduce it.
Thanks,
Qu
