mptcp: drop unused sk in mptcp_get_options
The parameter 'sk' became useless since the code using it was dropped from mptcp_get_options() in the commit 8d548ea1dd15 ("mptcp: do not set unconditionally csum_reqd on incoming opt"). Let's drop it. Signed-off-by: Geliang Tang <geliang.tang@suse.com> Signed-off-by: Matthieu Baerts <matthieu.baerts@tessares.net> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
