[PATCH 2/3] btrfs: qgroups, remove unnecessary memset before btrfs_init_work
From: Jeff Mahoneybtrfs_init_work clears the work struct except for ->wq, so the memset before calling btrfs_init_work in qgroup_rescan_init is unnecessary. We'll also initialize ->wq in btrfs_init_work so that it's obvious.
