e1000/rtl8139: update HMP NIC when every bit is written

Browse Source 
We currently just update the HMP NIC info when the last bit of macaddr
is written. This assumes that guest driver will write all the macaddr
from bit 0 to bit 5 when it changes the macaddr, this is the current
behavior of linux driver (e1000/rtl8139cp), but we can't do this
assumption.

The macaddr that is used for rx-filter will be updated when every bit
is changed. This patch updates the e1000/rtl8139 nic to update HMP NIC
info when every bit is changed. It will be same as virtio-net.
