media: v4l2-dv-timings: prevent possible overflow in v4l2_detect_gtf()
In v4l2_detect_gtf(), it seems safer to cast the 32-bit image_width
variable to the 64-bit type u64 before multiplying to avoid
a possible overflow. The resulting object code even seems to
look better, at least on x86_64.
Found by Linux Verification Center (linuxtesting.org) with Svace.
