#     crypto: af_alg - Initialize sg_num_bytes in error code path
#     
#     The RX SGL in processing is already registered with the RX SGL tracking
#     list to support proper cleanup. The cleanup code path uses the
#     sg_num_bytes variable which must therefore be always initialized, even
#     in the error code path.
