IB/hfi1: Remove state transition log message and opa_lstate_name()

Remove the state transition log message from the hfi1 driver, as
the IB core now logs the same information when handling a cache
update event.

While at it, replace the hfi1-specific opa_lstate_name() function with
the ib_verbs equivalent function, ib_port_state_to_str(), for converting
IB port state to a string.
