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);
