mptcp: check addrs list in userspace_pm_get_local_id
commit f012d796a6de662692159c539689e47e662853a8 upstream.
Before adding a new entry in mptcp_userspace_pm_get_local_id(), it's
better to check whether this address is already in userspace pm local
address list. If it's in the list, no need to add a new entry, just
return it's address ID and use this address.
Fixes: 8b20137012d9 ("mptcp: read attributes of addr entries managed by userspace PMs")
