------------------------------------------
Summary: "touchz" command should check quota limit before deleting
an already existing file

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.
