Subject: [PATCH v2 5/7] KVM: PPC: mmio: Queue interrupt at kvmppc_emulate_mmio

From: Fabiano Rosas <[email-masked]>
Date: Thu, 6 Jan 2022 17:03:02 -0300

If MMIO emulation fails, we queue a Program interrupt to the
guest. Move that line up into kvmppc_emulate_mmio, which is where we
set RESUME_GUEST/HOST.

No functional change, just separation of responsibilities.
