drm: zte: fix static checker warning on variable 'fmt'
Commit 4e986d3705df ("drm: zte: add overlay plane support") introduces
the following static checker warning:
drivers/gpu/drm/zte/zx_plane.c:170 zx_vl_rsz_setup()
warn: always true condition '(fmt >= 0) => (0-u32max >= 0)'
Fix it by change 'fmt' type to integer.
