colo-compare: Fix removing fds been watched incorrectly in finalization
We will catch the bellow error report while try to delete compare object
by qmp command:
chardev/char-io.c:91: io_watch_poll_finalize: Assertion `iwp->src == ((void *)0)' failed.
This is caused by failing to remove the right fd been watched while
call qemu_chr_fe_set_handlers();
Fix it by pass the worker_context parameter to qemu_chr_fe_set_handlers().
