KVM: Replace ->drop_interrupt_shadow() by ->set_interrupt_shadow()
This patch replaces drop_interrupt_shadow with the more general set_interrupt_shadow, that can either drop or raise it, depending on its parameter. It also adds ->get_interrupt_shadow() for future use. Signed-off-by: Glauber Costa <glommer@redhat.com> CC: H.
