fix: vty crash by logging to killed telnet session
When a telnet session dies (e.g. killall telnet) and also has logging enabled,
the closing of the telnet session logs to the killed telnet session and
segfaults: the vty->obuf is already NULL.
In vty_out(), guard against this situation by not composing an output if
vty->obuf is NULL.
Also guard all buffer_*() functions against a NULL buffer argument, which
should catch all other hypothetical code paths trying to add to a closed
vty->obuf.
