Lock all BOs used in gpuva ops and validate all BOs in a single step
during the VM bind IOCTL.
This help with the transition to making all gpuva ops in a VM bind IOCTL
a single atomic job which is required for proper error handling.
v2:
- Better commit message (Oak)
- s/op_lock/op_lock_and_prep, few other renames too (Oak)
- Use DRM_EXEC_IGNORE_DUPLICATES flag in drm_exec_init (local testing)
- Do not reserve slots in locking step (direction based on series from Thomas)
v3:
- Validate BO if is immediate set (Oak)
