Subject: [PATCH][next] crypto: sa2ul - Fix inconsistent IS_ERR and PTR_ERR

Fix inconsistent IS_ERR and PTR_ERR in sa_dma_init(). The proper pointer
to be passed as argument to PTR_ERR() is dd->dma_tx.

This bug was detected with the help of Coccinelle.

Fixes: 7694b6ca649f ("crypto: sa2ul - Add crypto driver")
