[PATCH mptcp-next v2 0/3] fixes for "add mptcp_subflow bpf_iter" v10

[Geliang Tang <geliang@kernel.org>]

From: Geliang Tang <tanggeliang@kylinos.cn>

v2:
 - drop unused variable 'err'.

There are two building errors in v10:

progs/mptcp_bpf_iters.c:24:8: error: call to undeclared function 'bpf_mptcp_sk'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
   24 |         msk = bpf_mptcp_sk((struct sock *)sk);
      |               ^
progs/mptcp_bpf_iters.c:24:6: error: incompatible integer to pointer conversion assigning to 'struct mptcp_sock *' from 'int' [-Wint-conversion]
   24 |         msk = bpf_mptcp_sk((struct sock *)sk);


tools/testing/selftests/bpf/prog_tests/mptcp.c: In function 'test_iters_subflow':
tools/testing/selftests/bpf/prog_tests/mptcp.c:546:13: error: unused variable 'err' [-Werror=unused-variable]
  546 |         int err;
      |             ^~~
  TEST-OBJ [test_progs] pe_preserve_elems.test.o

bpf_mptcp_sk() definition is missing. It will be used in patch 4.
An unused variable 'err' needs to be dropped.

Depends on:
 - "add mptcp_subflow bpf_iter" v10

Based-on: <cover.1729063444.git.tanggeliang@kylinos.cn>
