In the operational statistics notifications (both old and new
API) the driver receives the statistics per phy.
currently this statistics wasn't handled because they wasn't needed.

Now the channel_load_by_us parameter in these statistics will be used
for the link grading calculation (implemented in another patch),
so store its value in phy_ctxt.
