IB/hfi1: Send a pkey change event on driver pkey update
Swapping a cable from a "Mgmt Allowed=No" switch port to a "Mgmt Allowed=Yes" switch port doesn't send a pkey change notification. Therefore, the link doesn't become active as the oib_utils layer uses an old pkey table cache. Fix by ensuring the pkey change notification is sent when the table is changed both explicitly by the FM and implicitly by the driver via a cable swap.
