char: Use return values instead of error_is_set(errp)

Using error_is_set(errp) to check whether a function call failed is
fragile: it breaks when errp is null.  Check perfectly suitable return
values instead when possible.  As far as I can tell, errp can't be
null there, but this is more robust and more obviously correct
