This looks like a compiler problem - the variable is always initialized by validate_ntransact except when buf (which contains the smb) is null, when it returns -EINVAL and in that case pdata is not used. Setting it to null would not help anyway - if it were left as null it would oops on the memcpy (where pdata is used).
This area of code has not changed recently.
