fix: vty crash by logging during VTY_CLOSED event handling
When a VTY closes, dispatch the VTY_CLOSED signal before tearing down the VTY
buffer and fd.
In particular this fixes:
- a crash during telnet_close_client(), invoked by the VTY_CLOSED event, which
logs to DLGLOBAL and uses vty->obuf that, so far, vty_close() had already
unallocated earlier (OS#4164).
- the logging about closing a telnet session so far logged:
DLGLOBAL INFO Closing telnet connection r=NULL<->l=NULL
By dispatching the VTY_CLOSED event while the fd is still valid, we instead
get the actual connection IP address and port being closed:
DLGLOBAL INFO Closing telnet connection r=127.0.0.1:36708<->l=127.0.0.1:4258
Related: OS#4164
