[PATCH] i2c: imx: fix inconsistent IS_ERR and PTR_ERR

[Gustavo A. R. Silva]

Fix inconsistent IS_ERR and PTR_ERR in i2c_imx_dma_request.

The proper pointer to be passed as argument is dma->chan_tx.

This bug was detected with the help of Coccinelle.

Fixes: 5b3a23a3cc94 ("i2c: imx: notify about real errors on dma 
i2c_imx_dma_request")
