[Qemu-devel] [PATCH v2 master, stable-0.12] Don't load options roms intended to be loaded by the bios in qemu

[Avi Kivity]

The first such option rom will load at address 0, which isn't very nice,
and the second will report a conflict and abort, which is horrible.

Signed-off-by: Avi Kivity <address@hidden>

Changes from v1:
- use ->fw_file instead of ->addr to distinguish between host-loaded and
  firmware-loaded roms
- add the same check in a couple more places
