[PATCH net v3] net: sfp: improve Huawei MA5671a fixup

["Álvaro Fernández Rojas" <noltari@gmail.com>]

With the current sfp_fixup_ignore_tx_fault() fixup we ignore the TX_FAULT
signal, but we also need to apply sfp_fixup_ignore_los() in order to be
able to communicate with the module even if the fiber isn't connected for
configuration purposes.
This is needed for all the MA5671a firmwares, excluding the FS modded
firmware.

Fixes: 2069624dac19 ("net: sfp: Add tx-fault workaround for Huawei MA5671A SFP ONT")

 v3: avoid using a vendor name in the function
 v2: rebase on top of net/main instead of linux/master
