[PATCH 04/12] crypto: atmel-ecc - simplify probe error handling

[Lothar Rubusch]

Replace early return in atmel_ecc_probe() with explicit error handling
using a goto-based cleanup path.

Add comments to clarify client list insertion and algorithm registration
steps.

No functional change intended.
