QMP: Don't leak on connection close 

QMP's chardev event callback doesn't call
json_message_parser_destroy() on CHR_EVENT_CLOSED. As the call
to json_message_parser_init() on CHR_EVENT_OPENED allocates memory,
we'are leaking on close.

Fix that by just calling json_message_parser_destroy() on
CHR_EVENT_CLOSED.
