drm/amd/display: Explicitly cast v_total to signed in a subtraction
[WHY & HOW]
v_total is an uint32_t and subtracting an unsigned to a signed will
result in an unsigned which is always >= 0. As a result, the ternary
conditions are always true and thus has no effect.
This is fixed by casting v_total to signed explicitly. This also
avoids v_total subtraction to overflow.
This fixes 1 NO_EFFECT, 2 DEADCODE and 2 INTEGER_OVERFLOW issues reported
by Coverity.
