[PATCH][next] drm/mgag200: Fix uninitialized variable delta

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The variable delta is not initialized and this will cause unexpected
behaviour with the comparison of tmpdelta < delta. Fix this by setting
it to 0xffffffff. This matches the behaviour as in the similar function
mgag200_pixpll_compute_g200se_04.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 2545ac960364 ("drm/mgag200: Abstract pixel PLL via struct mgag200_pll")
