[Fedora 22] Disable dmesg output in console TTYs

Hello!

I am using Fedora 22 and for some reason the kernel ring buffer is being outputted to the console TTYs (tty3, tty4 ...). This is, for obvious reasons, a bit annoying when you are trying to use the TTYs without a GUI and I can't figure out how to fix it. In all the TTYs above tty6 it outputs the debug messages without letting you to login but I want to be able to login in the other ones and do stuff without being distracted by annoying debug messages while I am typing.

Edit: fixed the title a little.
