Gfs2-utils: gfs2-utils: stack out-of-bounds write via unchecked di_height in gfs2_edit

A stack out-of-bounds write vulnerability was found in gfs2-utils. In gfs2_edit, the di_height field from on-disk inode metadata is used as an array index without bounds checking, causing a stack buffer overflow that may lead to arbitrary code execution when processing crafted GFS2 filesystem images.
