virtio core already sets the .owner, so driver does not need to.

misc: Add Nitro Secure Module driver2023-11-28T19:05:16+00:00Alexander Grafgraf@amazon.com2023-10-11T21:35:22+00:00urn:sha1:b9873755a6c8ccfce79094c4dce9efa3ecb1a749
When running Linux inside a Nitro Enclave, the hypervisor provides a
special virtio device called "Nitro Security Module" (NSM). This device
has 3 main functions:
1) Provide attestation reports
2) Modify PCR state
3) Provide entropy
This patch adds a driver for NSM that exposes a /dev/nsm device node which
user space can issue an ioctl on this device with raw NSM CBOR formatted
commands to request attestation documents, influence PCR states, read
entropy and enumerate status of the device. In addition, the driver
implements a hwrng backend.
