scripts/kvm/kvm_stat: Invert dictionaries
Browse files Browse the repository at this point in the history 
The exit reasons dictionaries were defined number -> value but later
on were accessed the other way around. Therefore a invert function
inverted them.

Defining them the right way removes the need to invert them and
therefore also speeds up the script's setup process.
