net: sfp: fix PHY discovery for FS SFP-10G-T module
Commit 2f3ce7a56c6e ("net: sfp: rework the RollBall PHY waiting code")
changed the long wait before accessing RollBall / FS modules into
probing for PHY every 1 second, and trying 25 times.
Wei Lei reports that this does not work correctly on FS modules: when
initializing, they may report values different from 0xffff in PHY ID
registers for some MMDs, causing get_phy_c45_ids() to find some bogus
MMD.
Fix this by adding the module_t_wait member back, and setting it to 4
seconds for FS modules.
