During a dump, this attribute is essential, it enables the userspace to
know on which interface the context is linked to.

Fixes: 459aa660eb1d ("gtp: add initial driver for datapath of GPRS Tunneling Protocol (GTP-U)")

I target this to net, because I think this is a bug fix. The dump result cannot
be used if there is more than one gtp interface on the system.
