e1000e: remove RXSEQ link monitoring for serdes
RXSEQ interrupts were used to force link state interrogation of serdes links, as the Si was not guaranteed to report LSC interrupts when the link changed state. On some bladeservers this resulted in false link up reports if no link partner was connected. The RXSEQ treatment is not necessary, as the link can be monitored from the watchdog timer, and the false link indications cease.
