e1000e: do not toggle LANPHYPC value bit when PHY reset is blocked

When PHY reset is intentionally blocked on 82577/8/9, do not toggle the
LANPHYPC value bit (essentially performing a hard power reset of the
device) otherwise the PHY can be put into an unknown state.

Cleanup whitespace in the same function.
