Subject: [PATCH v2] scsi: qedf: Add port_id getter

Add qedf_get_host_port_id() to the transport template.

The fc_transport_template initializes the port_id member to the
default value of -1. The new getter ensures that the sysfs entry shows
the current value and not the default one, e.g by using 'lsscsi -H -t'

Signed-off-by: Daniel Wagner <dwagner@...e.de>

changes v2:
  - place closing brace on new line, fix whitespace damage
