conf: remove NULL check from virDomainQemuMonitorEventNew

The qemu_domain_monitor_event_msg struct in qemu_protocol.x
defines event as a nonnull_string and qemuMonitorJSONIOProcessEvent
also errors out on a non-NULL event.

Drop the check to fix the build with static analysis.

This essentially reverts commit d343e8203d
