Samuel Sapalski f25d254dfd decompress_gunzip: Fix DoS if gzip is corrupt 
On certain corrupt gzip files, huft_build will set the error bit on
the result pointer. If afterwards abort_unzip is called huft_free
might run into a segmentation fault or an invalid pointer to
free(p).

In order to mitigate this, we check in huft_free if the error bit
is set and clear it before the linked list is freed.
