Return error when no core is available

In addition, clone tries to use the next vacant hyper-threading
core instead of trying to use next vacant hyper-threading core
of the next vacant physical core.

use PF_POPULATE for resolving delegated page faults
...
Since a host side PTE does not follow McKernel's copying a COW page,
COW pages cannot be used for resolving delegated page faults.
Therefore, to copy pages eagerly, PF_POPULATE should be used.
