d4044c2a6b e1000: use MII status register for link up/down
Some guests will use the standard MII status register
to verify link state.  They will not notice link changes
unless this register is updated.

Verified with Linux 3.0 and Windows XP guests.

Without this patch, ethtool will report speed and duplex as
unknown when the link is down, but still report the link as
up.  This is because the Linux e1000 driver checks the
mac_reg[STATUS] register link state before it checks speed
and duplex, but uses the phy_reg[PHY_STATUS] register for
the actual link state check.  Fix by updating both registers
on link state changes.
