pgcrypto: Check for error return of px_cipher_decrypt()

This has previously not been a problem (that anyone ever reported),
but in future OpenSSL versions (3.0.0), where legacy ciphers are/can
be disabled, this is the place where this is reported.  So we need to
catch the error here, otherwise the higher-level functions would
return garbage.  The nearby encryption code already handled errors
similarly.
