[Mesa-dev] [PATCH] anv: Fix unintentional integer overflow in anv_CreateDmaBufImageINTEL

[Mun Gwan-gyeong]

pCreateInfo->strideInBytes * pCreateInfo->extent.height with type
"unsigned int" is evaluated using 32-bit arithmetic.
This fixes unintentional integer overflow by casting to uint64_t before
multifying.
