bios_emulator: fix incorrect printing of address in "call near immediate"

In the x86emuOp_call_near_IMM() function the address of CALL is
printed incorrectly when jumping backwards. For example, the correct
disassemble of the bytes below would be:

0000E8DE  E8DBFF            call 0xe8bc

(verified by ndisasm). But instead the address is printed as "ffffe8bc".
That's because of the following macro:

    DECODE_PRINTF2("%04x\n", ip);

while it should be

    DECODE_PRINTF2("%04x\n", (u16)ip);
