net: sfp: add potron quirk to the H-COM SPP425H-GAB4 SFP+ Stick

commit a92a6c50e35b75a8021265507f3c2a9084df0b94 upstream.

This is another one of those XGSPON ONU sticks that's using the
X-ONU-SFPP internally, thus it also requires the potron quirk to avoid tx
faults. So, add an entry for it in sfp_quirks[].
