vl.c: Don't print errno after failed qemu_chr_new()
The qemu_chr_new() function doesn't set errno on failure, so
don't print strerror(errno) on the error handling path when
dealing with the -serial, -parallel and -virtioconsole arguments.
This avoids nonsensical error messages like:
$ ./arm-softmmu/qemu-system-arm -serial wombat
qemu: could not open serial device 'wombat': Success
We also rephrase the message slightly to make it a little clearer
that we're expecting the name of a QEMU chr backend rather than
a host or guest serial/parallel/etc device.
