Btrfs: fix a warning when updating qgroup limit
Step to reproduce:
mkfs.btrfs <disk>
mount <disk> <mnt>
btrfs quota enable <mnt>
btrfs qgroup limit 0/1 <mnt>
dmesg
If the relative qgroup dosen't exist, flag 'BTRFS_QGROUP_STATUS_
FLAG_INCONSISTENT' will be set, and print the noise message.
This is wrong, we can just move find_qgroup_rb() before
update_qgroup_limit_item().this dosen't change the logic of the
function. But it can avoid unnecessary noise message and wrong set of flag.
