net: sfp: re-attempt probing for phy
Some 1000BASE-T PHY modules take a while for the PHY to wake up.
Retry the probe a number of times before deciding that the module has
no PHY.
Tested with:
Sourcephotonics SPGBTXCNFC - PHY takes less than 50ms to respond.
Champion One 1000SFPT - PHY takes about 200ms to respond.
Mikrotik S-RJ01 - no PHY
