gtp: fix a potential NULL pointer dereference
When sockfd_lookup() fails, gtp_encap_enable_socket() returns a
NULL pointer, but its callers only check for error pointers thus miss
the NULL pointer case.
Fix it by returning an error pointer with the error code carried from
sockfd_lookup().
(I found this bug during code inspection.)
Fixes: 1e3a3abd8b28 ("gtp: make GTP sockets in gtp_newlink optional")
