tg3: allow ethtool -p to work for NICs in down state

Browse source 
Make tg3 behave like other drivers and let "ethtool -p" identify the
NIC even when it's in the DOWN state. Before this patch it would get an
error as follows if the NIC was down:

# ip link set down dev em4
# ethtool -p em4
Cannot identify NIC: Resource temporarily unavailable

With this patch ethtool identify works regardless of whether the NIC is up
or down as it does for other drivers.
