[PATCH -next] crypto: qce: skcipher: fix error return code in qce_skcipher_async_req_handle()

[Wei Yongjun]

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 1339a7c3ba05 ("crypto: qce: skcipher: Fix incorrect sg count for dma transfers")
