KVM: s390: Fix printk on SIGP set arch

KVM on s390 does not support the ESA/390 architecture. We refuse to
change the architecture mode and print a warning. This patch removes
the printk for several reasons:

o A malicious guest can flood host dmesg
o The old message had no newline
o there is no connection between the message and the failing guest

This patch simply removes the printk. We already set the condition
code to 3 - the guest knows that something went wrong.
