vp8,get_sub_mv_ref_prob: change arguments to uint32_t

this matches the call with int_mv::as_int and fixes a warning with
clang-13 -fsanitize=integer:
vp8/decoder/decodemv.c:240:32: runtime error: implicit conversion from
type 'uint32_t' (aka 'unsigned int') of value 4282515456 (32-bit,
unsigned) to type 'int' changed the value to -12451840 (32-bit, signed)
