[SCSI] zfcp: Fix wka port processing
Under certain conditions it is possible that a WKA port ist not opened
within the expected timeframe of half a second. In this situation
the WKA port remains in the state OPENING preventing any succeding
request to open the port. This led to unrecoverable remote ports.
Fixing this by always setting an appropriate WKA port status before
leaving the function and removing the timeout value here since it's
not needed here because the general timeout processing would deal
with it if required.
