[Qemu-devel] [PATCH v2 2/6] char-fe: set_handlers() needs an associated chardev |

It is futile to call qemu_chr_fe_set_handlers() without an associated
chardev, because the function is doing nothing in that case, not even
reporting an error, it would likely be a programming error. Let's not
handle that hypothetical case.
(fwiw, I introduced the check in commit
94a40fc56036b5058b0b194d9e372a22e65ce7be, that was a mistake imho)
