ipa: Allow users closing lower layer tcp/ipa connections
This is useful for users to abort connections which are in "connecting"
state, since the higher layer struct e1inp_sign_link is not provided to
the user until the TCP+IPA handshake in the socket becomes fully
established (sign_link_up() callback).
This is intended for osmo-bts: when something fails and may enter into
SHUTDOWN state, it is desirable to close new RSL links (sockets) which
are in progress to connect, while it waits for a while to complete
shutdown (power ramping down, etc.).
