crypto: ccp - Fix sample application signature passing
When parameters are sent the PSP returns back it's own signature
for the application to verify the authenticity of the result.
Display this signature to the caller instead of the one the caller
sent.

Fixes: febe3ed3222f ("crypto: ccp - Add a sample library for ioctl use")
