chardev: Fix record/replay error path NULL deref in device creation
qemu_chardev_set_replay() was being called in chardev creation to
set up replay parameters even if the chardev is NULL.
A segfault can be reproduced by specifying '-serial chardev:bad' with
an rr=record mode.
Fix this with a NULL pointer check.
