lightningd: don't explicitly tell connectd to disconnect, have it do it on sending error/warning.

Connectd already does this when we *receive* an error or warning, but
now do it on send.  This causes some slight behavior change: we don't
disconnect when we close a channel, for example (our behaviour here
has been inconsistent across versions, depending on the code).

When connectd is told to disconnect, it now does so immediately, and
doesn't wait for subds to drain etc.  That simplifies the manual
disconnect case, which now cleans up as it would from any other
disconnection when connectd says it's disconnected.
