kvm_stat: Fix the non-x86 exit reasons

Browse source 
In kvm_stat we have a dictionary of exit reasons for s390. Firstly these
are not s390 specific, they are the generic exit reasons. So rename the
dictionary to reflect that, and add it separately to filters[].

Secondly, the values are defined using hex, but in the kernel header
they are decimal. That means values above 9 in kvm_stat are incorrect.

While we're there, fix the whitespace to match the rest of the file.
