Arm SCMI fixes for v6.2
Few fixes addressing:
1. Possible compromise with the shorter message size from a misbheaving
SCMI platform firmware. The shmem accesses are now hardened to handle
the same in fetch_notification and fetch_response.
2. Possible unsafe locking scenario which is solved by calling
virtio_break_device() before getting hold of vioch->lock.
3. Possible stale error status reported from a previous message being
used again as it is not cleared.
