The LLDDs report events to libsas with .notify_port_event and
.notify_phy_event callbacks.

These callbacks are fixed and so there is no reason why we cannot call the
functions directly, so do that.

This neatens the code slightly.

Don't forget your signed-off-by :)

When sas_register_ha() returns, those are set and can be
  called by the LLDD to notify the SAS layer of such events

Maybe this was missed in the rebase, but I think that this comment can go/be changed at some stage.

Thanks,
John
