touchz: The NameSpace quota (directories and files) of directory /dir2 is exceeded: quota=3 file count=5

Here, the "touchz" command failed to create the file as the quota limit was hit, but ended up deleting the original file which existed. It should do the quota check before deleting the file so that after successful deletion, creation should succeed.
