drm/exynos: fix a timeout loop
We were trying to print an error message if we timed out here, but the
loop actually ends with "tries" set to UINT_MAX and not zero. Fix this
by changing from tries-- to --tries.
A for loop would actually be the most natural way to do this. My fix
means we only loop 99 times instead of 100 but that's probably ok.
