[PATCH 1/2 v2] dcc: free glz buffer after zlib compression

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

For zlib+glz compression image if first compressed with glz then the
resulting buffer is compressed again with zlib then the buffer from
zlib is returned to the caller.
However the temporary glz buffer was not freed resulting in a memory
leak.
