Instaslice objects should not be created for the nodes that do not have MIG enabled GPUs

[harche]

In my testing I observed that the instaslice objects were created (and they were missing status) for the nodes that have the relevant GPUs but those GPUs do not have the MIG mode enabled. For such cases, there shouldn't have been any instaslice object to begin with.
