mptcp: Remove redundant assignments in path manager init
A few members of the mptcp_pm_data struct were assigned to hard-coded values in mptcp_pm_data_reset(), and then immediately changed in mptcp_pm_nl_data_init(). Instead, flatten all the assignments in to mptcp_pm_data_reset(). v2: Resolve conflicts due to rename of mptcp_pm_data_reset() v4: Resolve conflict in mptcp_pm_data_reset() Acked-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
