perf kvm: Simplify exit reasons tables definitions

The perf_kvm_stat struct keeps the size of a table of exit reasons in
the field 'exit_reasons_size'.

The field is initialized and then used by get_exit_reason() for serial
access to the table, so that the calling function does not actually need
to know table size.

Usage of tables with 'end of sequence' marker simplifies the
get_exit_reason() function.

Also the patch introduces a define_exit_reasons_table, which makes it
easier to define new tables.
