Fixed error when compiling migration/qemu-file.c with 
as shown here:

../migration/qemu-file.c: In function 'qemu_get_buffer_in_place':
../migration/qemu-file.c:604:18: error: 'src' may be used uninitialized in this 
function [-Werror=maybe-uninitialized]
  604 |             *buf = src;
      |             ~~~~~^~~~~
