[PATCH 2/4] net: sfp: allow to use also SFP modules which are detected as SFF

[Pali Rohár]

Some GPON SFP modules (e.g. Ubiquiti U-Fiber Instant) have set SFF phys_id
in their EEPROM. Kernel SFP subsystem currently does not allow to use
modules detected as SFF.

This change extends check for SFP modules so also those with SFF phys_id
are allowed. With this change also GPON SFP module Ubiquiti U-Fiber Instant
is recognized.
