From: Blue Swirl <blauwirbel@gmail.com>

When building on a 64 bit host which uses 'long' for int64_t,
GCC emits a warning:
  CC    block/blkverify.o
/src/qemu/block/blkverify.c: In function `blkverify_verify_readv':
/src/qemu/block/blkverify.c:304: warning: long long int format, long
unsigned int arg (arg 3)

Rework a77cffe7e916f4dd28f2048982ea2e0d98143b11 to avoid the warning.
