net: sfp: improve Nokia GPON sfp fixup

Improve the Nokia GPON fixup - we need to ignore not only the hardware
LOS signal, but also the software implementation as well. Do this by
using the new state_ignore_mask to indicate that we should ignore not
only the hardware RX_LOS signal, and also clear the LOS bits in the
option field.
