Fix potiential seg fault if user doesn't specify BootDevices attribute
Fix potiential seg fault if user doesn't specify BootDevices attribute

If the user doesn't specify the BootDevices attribute, then we should return
from the bootord_vssd_to_domain().  Otherwise, the provider will seg fault when
it tries to get the length of the array.  Since specifying a boot order is
optional, set the boot order count to 0 and return.
