Change in osmo-sgsn[master]: libgtp: don't call sgsn_pdp_ctx_free() with NULL pdp

[Keith Whyte]

Hello lynxis lazus, Jenkins Builder, 

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

    https://gerrit.osmocom.org/13929

to look at the new patch set (#3).

Change subject: libgtp: don't call sgsn_pdp_ctx_free() with NULL pdp
......................................................................

libgtp: don't call sgsn_pdp_ctx_free() with NULL pdp

In [osmo-ggsn]:gtp.c:gtp_delete_pdp_conf():

When the condition pdp_getgtp1(&pdp, get_tei(pack)) returns true
we then call gsn->cb_conf(type, EOF, NULL, cbp);

This NULL pdp will cause a crash later in
delete_pdp_conf()
  sgsn_pdp_ctx_free()
    rate_ctr_group_free()

So just return on NULL pdp to prevent this crash.
