sgsn: Fix deeply flawed copying logic for PDP context activation

It is one of these changes that should have never worked but did
for a long time. Only recently a corrupted GTP message was seen.
The code in ccd2312d10e14747e8a4d26d8f72b052ffcfc282 tried to
solve the right problem but was deeply flawed.

* Make the code operate on the copied message and not the original
one that is deleted by the underlaying layers on return
* Add an out variable to determine if the msgb should be deleted
and assume that by default it will be deleted.
