The check for `!fbc || (fbc->common.fn_flags & ZEND_ACC_VARIADIC)` is performed after `fbc` is set to NULL, so this always returns true. This results in `ZEND_FCALL_MAY_HAVE_EXTRA_NAMED_PARAMS` always being set for unpack sends. Fix it by moving the flag updates to the point before setting `fbc` to NULL.
