s/Intel: fix/anv: fix: potentially overflowing expression in genX

Browse Source 
CID 1528164 (#1 of 1): Unintentional integer overflow (OVERFLOW_BEFORE_WIDEN)
overflow_before_widen: Potentially overflowing expression
pool->n_passes * pool->khr_perf_preamble_stride with type
unsigned int (32 bits, unsigned) is evaluated using 32-bit arithmetic,
and then used in a context that expects an expression of type uint64_t (64 bits, unsigned).
