IB/hfi1: Remove lstate from hfi1_pportdata

Browse Source 
Do not track logical state separately from host_link_state. Deduce
logical state from host_link_state when required. Transitions in
set_link_state and goto_offline already make sure host_link_state
reflects hardware's logical state properly.
