net: Return errno in sk->sk_prot->get_port().
[ Upstream commit 7a7160edf1bfde25422262fb26851cef65f695d3 ]
We assume the correct errno is -EADDRINUSE when sk->sk_prot->get_port()
fails, so some ->get_port() functions return just 1 on failure and the
callers return -EADDRINUSE instead.
However, mptcp_get_port() can return -EINVAL. Let's not ignore the error.
Note the only exception is inet_autobind(), all of whose callers return
-EAGAIN instead.
Fixes: cec37a6e41aa ("mptcp: Handle MP_CAPABLE options for outgoing connections")
