s390x/ioinst: pass the retaddr to all IO instructions 

TCG needs the retaddr when injecting an interrupt. Let's just pass it
along and use RA_IGNORED for KVM. The value will be completely ignored for
KVM.

Convert program_interrupt() to s390_program_interrupt() directly, making
use of the passed address.
