sgsn_libgtp: fix NULL dereference in cb_delete_context()

sgsn_pdp_ctx_free() contains an abnormal path (with a backtrace log)
for the case where a PDP context is freed while its libgtp handle is
still attached.  In that path, lib->priv is set to NULL to prevent
other callbacks (e.g. cb_data_ind()) from dereferencing the already-
freed sgsn_pdp_ctx.

When libgtp subsequently calls cb_delete_context() as part of its own
teardown, pdp->priv is NULL, causing an immediate NULL dereference at
the pctx->lib = NULL assignment.

Guard against this by returning early when priv is NULL: the SGSN-side
context is already gone, so there is nothing left for the callback to do.
