util/hexdump: Reorder qemu_hexdump() arguments

qemu_hexdump()'s pointer to the buffer and length of the
buffer are closely related arguments but are widely separated
in the argument list order (also, the format of <stdio.h>
function prototypes is usually to have the FILE* argument
coming first).

Reorder the arguments as "fp, prefix, buf, size" which is
more logical.
