commit 03cb4c2d66bf4a9890e74557a2533a8d70a4880b

gtp_build_payload(): Support absent peer and SGSN address
When deleting a PDP context via "gtp-tunnel delete", we specify only
the gtp netdevice, the gtp version and the TID/TEI. However, the
gtp_build_payload() function unconditionally created the netlink
attributes for GTPA_PEER_ADDRESS and GTPA_MS_ADDRESS, having their
addresses set to zero. The kernel then tried to find a PDP context with
MS and PEER address of 0.0.0.0, and always failed with ENOENT.
The same problem also occurred with OsmoGGSN and OpenGGSN: PDP contexts
could be added but never removed.
The corresponding kernel change that requires this userland change
is the following commit introduced in 4.12-rc1:

gtp: unify genl_find_pdp and prepare for per socket lookup
Older kernels will work with libgtpnl both before and after this commit,
as they internally will simply disregard any attributes beyond TID/TEI.
