chardev: don't exit() straight away on C-a x
While there are a number of uses in the code-base of the exit(0)
pattern it gets in the way of clean exit which can do all of it's
house-keeping. In particular it was reported that you can crash
plugins this way because TCG can still be running on other threads
when the atexit callback is called.
Use qmp_quit() instead which takes care of some housekeeping before
triggering the shutdown.
