This is a first step in removing any printing from
ref-filter formatting logic, so that it could be more general.
Everything would be the same for show_ref_array_item() users.
But, if you want to deal with errors by your own, you could invoke
format_ref_array_item(). It means that you need to print everything
(the result and errors) on your side.
This commit changes signature of format_ref_array_item() by adding
return value and strbuf parameter for errors, and adjusts
its callers. While at it, reduce the scope of the out-variable.
