Just setting a reasonable error string using error_setg() is
simpler and makes error messages clearer.

Before:

  $ qemu-system-s390x -device x-terminal3270,devno=x
  qemu-system-s390x: -device x-terminal3270,devno=x: Property 'x-terminal3270.devno' doesn't take value 'x'

After:

  $ qemu-system-s390x -device x-terminal3270,devno=x
  qemu-system-s390x: -device x-terminal3270,devno=x: Property 'x-terminal3270.devno' can't take value 'x': invalid devno
