qemu-char: Set foo_tag = 0 when returning FALSE from callbacks
While reviewing some patches I found this problem where tcp_chr_accept does not clear listen_tag when returning FALSE, leading to a double g_source_remove of the underlying source. Not really a problem unless the id gets re-used in between, but still something we should fix. While at it I've also reviewed all the other code in qemu-char.c for similar problems and found that pty_chr_timer has the same problem.
