hw/display: check frame buffer can hold blob

Coverity reports (CID 1564769, 1564770) that we potentially overflow
by doing some 32x32 multiplies for something that ends up in a 64 bit
value. Fix this by first using stride for all lines and casting input
to uint64_t to ensure a 64 bit multiply is used.
