e1000e: workaround for packet drop on 82579 at 100Mbps

commit 0ed013e28fe853244f4972cf18d8e2bd62eeb8fc upstream.

The MAC can drop short packets when the PHY detects noise on the line at
100Mbps due to a timing issue.  Workaround the issue by increasing the PLL
counter so the PHY properly recognizes the synchronization pattern from the
MAC.
