From: Qu Wenruo <wqu@xxxxxxxx>
Commit 078e9a1cc973 ("btrfs-progs: check: enhanced progress indicator")
introduced @qgroup_item_count for progress indicator.
However since we will later introduce silent qgroup rescan
functionality, the @qgroup_item_count pointer can be NULL.
So check if @qgroup_item_count is NULL before accessing it.
