Brian Gianforcaro cb45b2c001 Kernel: Make AnonymousVMObject::clone() API OOM safe ...

Propagate allocation failure of m_shared_committed_cow_pages,
and uncommit previously committed COW pages on failure.

This method needs a closer look in terms of error handling, as we
will eventually need to rollback all changes on allocation failure.
Alternatively we could allocate the anonymous object much earlier
and only initialize it once the other steps have succeeded.
