[PATCH] xfs: destroy mutex qi_tree_lock before free xfs_quotainfo_t object

[Xiongwei Song]

The mutex qi_tree_lock of xfs_quotainfo_t object was initialized when
calling xfs_qm_init_quotainfo, but it was not destroyed before free
xfs_quotainfo_t object when calling xfs_qm_destroy_quotainfo, this was
incorrect, so destroy it in function xfs_qm_destroy_quotainfo.
