I have no idea if we can have more than one vmware_vga device, so play
it safe.

FWIW, it doesn't look like it's possible:

$ ./qemu-system-x86_64 -device vmware-svga  -device vmware-svga
RAMBlock "vmsvga.fifo" already registered, abort!
Aborted (core dumped)

(NB: Aborting is very user-unfriendly here, but that's something for another 
patch...)
