1. Add guest driver CUID support
2. Do not expose vf index(variable "fcn_idx") to customers,
replace the fcn_idx with pad.
Only expose the unitid to customers.

As far as I can see that is overkill, please use debugfs_create_x64() and debugfs_create_x8() instead.

Debugfs should never have error handling. Please drop that.
