David Majnemer c83044d9bb [FunctionAttrs] Don't try to infer returned if it is already on an argument ...

Trying to infer the 'returned' attribute if an argument is already
'returned' can lead to verification failure: inference might determine
that a different argument is passed through which would result in two
different arguments marked as 'returned'.

This fixes PR30350.
