Stefan Hajnoczi 0d108681ac [comboot] Propagate carry flag from COMBOOT API ...

COMBOOT API calls set the carry flag on failure.  This was not being
propagated because the COMBOOT interrupt handler used iret to return
with EFLAGS restored from the stack.  This patch propagates CF before
returning from the interrupt.
