KVM: arm64: vgic-its: Make vgic_its_cmd_handle_mapi similar to other handlers
vgic_its_cmd_handle_mapi has an extra "subcmd" argument, which is already contained in the command buffer that all command handlers obtain from the command queue. Let's drop it, as it is not that useful. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
