panvk: cast negative value to unint8_t
The index is a uint8_t but can be assigned a negative 1
value in panvk_pipeline_builder_parse_color_blend()
The comparison to ~0 thus makes sense but clang will complain:
"result of comparison of constant -1 with expression of type
'const uint8_t' (aka 'const unsigned char') is always true
[-Wtautological-constant-out-of-range-compare]"
Fix this by casting to a uint8_t before comparison.
Fixes a warning with clang
