tools/kvm_stat: fix missing field update after filter change
When updating the fields filter, tracepoint events of fields previously not visible were not enabled, as TracepointProvider.update_fields() updated the member variable directly instead of using the setter, which triggers the event enable/disable. To reproduce, run 'kvm_stat -f kvm_exit', press 'c' to remove the filter, and notice that no add'l fields that do not match the regex 'kvm_exit' will appear. This issue was introduced by commit c469117df059 ("tools/kvm_stat: simplify initializers"). Signed-off-by: Stefan Raspl <raspl@linux.vnet.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
