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.
