qemu/tests/qtest/pflash-cfi02-test.c
Peter Maydell 909e4a0826 tests/qtest/pflash-cfi02-test: Avoid potential integer overflow 
Coverity points out that we calculate a 64-bit value using 32-bit
arithmetic; add the cast to force the multiply to be done as 64-bits.
(The overflow will never happen with the current test data.)

Fixes: Coverity CID 1432320
