r8169: inline rtl8169_make_unusable_by_asic
Inline rtl8169_make_unusable_by_asic() and simplify it:
- Address field doesn't need to be poisoned because descriptor is
owned by CPU now
- desc->opts1 is set by rtl8169_mark_to_asic() and rtl8169_rx_fill(),
therefore we don't have to preserve any field parts.
