drm/amd/display: fix for-loop with incorrectly sized loop counter (v2)
A for-loop is iterating from 0 up to 1000 however the loop variable count
is a u8 and hence not large enough. Fix this by making count an int.
Also remove the redundant initialization of count since this is never used
and add { } on the loop statement make the loop block clearer.
v2: drop useless else (Walter Harms)
Addresses-Coverity: ("Operands don't affect result")
