devtool: edit-recipe: fix regression
OE-Core commit
5a16b3c804c5eca331a1c08a7ce31a54909af105 attempted to use
the same function to get the path to a recipe as the new "find-recipe"
command it implemented, except that cannot work because (a) it didn't
return anything and (b) event if it had tried, a command function can
only return an exit code and we don't want that for find-recipe if it
succeeded. Split out a separate reusable function for both commands.
