[Qemu-devel] ivshmem crash bug

"-device ivshmem" makes pci_ivshmem_init() pass null pointer to
shm_open().  Suspect the "Must specify 'chardev' or 'shm' to ivshmem"
error should be fatal.

By the way, that error message can be misleading: the chardev must be
"unix:" to be recognized.  For instance, "-chardev null,id=chr0 -device
ivshmem,chardev=chr0" isn't.
