looking around the internet this comes with some stock devices such as nexus 5.It is listed as an app this is critical for phone functioning.Furthermore Qualcomm is your chipset so it is best left untouched.

How to stop this

Welcome.
The reply given by @Sathu777 is not to your liking? You wish to stop your phone functioning properly?

There's not much information on com.qualcomm.shutdownlistener, but it's moist likely the daemon that listens for shutdown signals. If you stop it, you probably can't shut the phone off. That wouldn't be too nice, even if you could remove the battery every time you wanted to shut it off.
