net, sockmap: Don't call bpf_prog_put() on NULL pointer
If bpf_prog_inc_not_zero() fails for skb_parser, then bpf_prog_put() is
called unconditionally on skb_verdict, even though it may be NULL. Fix
and tidy up error path.
Fixes: 743df8b7749f ("bpf, sockmap: Check skb_verdict and skb_parser programs explicitly")
Addresses-Coverity-ID: 1497799: Null pointer dereferences (FORWARD_NULL)
