e1000e: correct MAC-PHY interconnect register offset for 82579

The MAC-PHY interconnect register set on ICH/PCH parts is accessed through
a peephole mechanism by writing an offset to a CSR register.  The offset
for the interconnect's half-duplex control register (which is used in a
jumbo frame workaround for 82579) is incorrect.
