sctp: fix err_chunk memory leaks in INIT handling

When sctp_verify_init() encounters unrecognized parameters, it allocates an err_chunk to report them. However, this chunk is leaked in several code paths:

  • In sctp_sf_do_5_1B_init(), if security_sctp_assoc_request() fails after
sctp_verify_init() has populated err_chunk, the function returns immediately without freeing it.
  • In sctp_sf_do_unexpected_init(), the same leak occurs on the
security_sctp_assoc_request() failure path.
  • In sctp_sf_do_unexpected_init(), on the success path after copying
unrecognized parameters to the INIT-ACK, the function returns without freeing err_chunk, unlike sctp_sf_do_5_1B_init() which properly frees it.

Fix all three leaks by adding sctp_chunk_free(err_chunk) calls before returning in the error paths and on the success path in sctp_sf_do_unexpected_init().
