[PATCH 5/7] qemu-kvm: Move gsi bits from kvm_msix_vector_add to kvm_msi_add_message

[Jan Kiszka <jan.kiszka@xxxxxx>]

From: Jan Kiszka <jan.kiszka@xxxxxxxxxxx>

Testing support and allocating a GSI for an MSI message is required both
for MSI and MSI-X. At this chance, drop the aging version warning.
