It is possible that certain QEMU configurations may not
create an IPLB (such as when -kernel is provided). In
this case, a misleading error message will be printed
stating that the "boot menu is not supported for this
device type".

To amend this, only print this message iff boot menu=on
was provided on the commandline. Otherwise, return silently.

Nit: make the prefix s390x/ipl:, as this is not directly in the bios.

This change makes sense and works as I'd expect (although the message
is still slightly odd in the -kernel case, but I can't think of
anything better.)

Will you also do a followup removing the trailing punctuation? :)
