net: sfp-bus: fix SFP mode detect from bitrate
The referenced commit moved the setting of the Autoneg and pause bits
early in sfp_parse_support(). However, we check whether the modes are
empty before using the bitrate to set some modes. Setting these bits
so early causes that test to always be false, preventing this working,
and thus some modules that used to work no longer do.
Move them just before the call to the quirk.
