[Qemu-devel] [PATCH v2] s390/ipl: only print boot menu error if -boot menu=on was specified

["Collin L. Walling" <walling@linux.vnet.ibm.com>]

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.

While we're at it, remove trailing periods from error
messages.
