crypto: af_alg - cast ki_complete ternary op to int 

commit 64e7f852c4 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.
