hw/mips/malta: Silence warning from ubsan
When compiling QEMU with --enable-ubsan there is a undefined behavior
warning when using the malta machine:

 hw/mips/malta.c:1200:32: runtime error: addition of unsigned offset
  to 0x7fb620600000 overflowed to 0x7fb6205fffff
 SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior hw/mips/malta.c:1200:32

To fix the issue, check the bios_size whether we really loaded the
firmware before trying to byte-swap the instructions here.
