Change in ...osmo-sgsn[master]: sgsn: Reject PdpActReq if no GTP pdp ctx exists

[pespin]

Hello lynxis lazus, Jenkins Builder, 

I'd like you to reexamine a change. Please visit

    https://gerrit.osmocom.org/c/osmo-sgsn/+/15330

to look at the new patch set (#2).

Change subject: sgsn: Reject PdpActReq if no GTP pdp ctx exists

sgsn: Reject PdpActReq if no GTP pdp ctx exists

It could happen that SGSN drops GTP side of a pdp ctx (pdp->lib=NULL)
while still maintaing the other side (to notify about the entire pdp ctx
being torn down). If a PdpActReq arrives during that time, we need to
account for that situation, otherwise osmo-sgsn crashes accessing
pdp->lib.
If no pdp->lib is found at that time, let's reject the request and
expect at some point later in time the entire pdp context will be
destroyed and reestablished.
