device/oprom/realmode/x86: temporary disable NULL breakpoints

Disable NULL breakpoints in setup_realmode_idt before calling
write_idt_stub in a loop.

TEST=No more spurious Null dereference errors in the console output.
Before Mandolin showed these two errors before running the VBIOS:

[ERROR]  Null dereference at eip: 0x4e6f1a35
[ERROR]  Null dereference at eip: 0x4e6f1a4f
