KVM: selftests: Don't bother deleting memslots in KVM when freeing VMs

When freeing a VM, don't call into KVM to manually remove each memslot,
simply cleanup and free any userspace assets associated with the memory
region.  KVM is ultimately responsible for ensuring kernel resources are
freed when the VM is destroyed, deleting memslots one-by-one is
unnecessarily slow, and unless a test is already leaking the VM fd, the
VM will be destroyed when kvm_vm_release() is called.

Not deleting KVM's memslot also allows cleaning up dead VMs without having
to care whether or not the to-be-freed VM is dead or alive.
