Remove redundant error code definitions

We're including psa/crypto_values.h, which defines the necessary error
codes. Remove redundant definitions, which hurt because they need to be
styled in exactly the same way (same presence/absence of spaces between
tokens).

This completes the fix of https://github.com/Mbed-TLS/mbedtls/issues/6875.
