Commit message: Fix division by zero

Fix uclouvain/openjpeg#733
CVE: CVE-2016-4797
CWE: CWE-369
Vulnerability description: Divide-by-zero vulnerability in the opj_tcd_init_tile function in tcd.c in OpenJPEG before 2.1.1 allows remote attackers to cause a denial of service (application crash) via a crafted jp2 file. NOTE: this issue exists because of an incorrect fix for CVE-2014-7947.
