crypto: ccp - Fix DBC sample application error handling
The sample application was taking values from ioctl() and treating
those as the error codes to present to a user.
This is incorrect when ret is non-zero, the error is stored to `errno`.
Use this value instead.
Fixes: f40d42f116cf ("crypto: ccp - Add a sample python script for Dynamic Boost Control")
Fixes: febe3ed3222f ("crypto: ccp - Add a sample library for ioctl use")
