xen/privcmd: return -ENOTTY for unimplemented IOCTLs
The code sets the default return code to -ENOSYS but then overrides this to -EINVAL in the switch() statement's default case, which is clearly silly. This patch removes the override and sets the default return code to -ENOTTY, which is the conventional return for an unimplemented ioctl.
