commit 64e7f852c47ce99f6c324c46d6a299a5a7ebead9 upstream.
when libkcapi test is executed using HW accelerator, cipher operation return -74.Since af_alg_async_cb->ki_complete treat err as unsigned int, libkcapi receive 429467222 even though it expect -ve value.
Hence its required to cast resultlen to int so that proper error is returned to libkcapi.
