The print_xstate_features() invokes print_xstate_feature() multiple
times in separate lines which can be replaced with a loop.
The print_xstate_feature() function already checks the feature
enabling status, and it is only called from within
print_xstate_features(). So the code can be relocated.
Move the code exactly to print_xstate_features() and wrap it with a
loop there.
