Subject: [PATCH] btrfs-progs: check: initialize qgroup_item_count in earlier stage
Git-commit: 8ca6c0c3c718
Patch-mainline: v5.2.1
References: bsc#1158560

"btrfsck -Q" segfaults because it does not call qgroup_set_item_count_ptr()
Properly: 

  # btrfsck -Q /dev/sdk
  Opening filesystem to check...
  Checking filesystem on /dev/sdk
  UUID: 34a35bbc-43f8-40f0-8043-65ed33f2e6c3
  Print quota groups for /dev/sdk
  UUID: 34a35bbc-43f8-40f0-8043-65ed33f2e6c3
  Segmentation fault (core dumped)

Since "struct task_ctx ctx" is global, we can just move
qgroup_set_item_count_ptr() much earlier stage in the check process to
avoid to forget initializing it.
