[v2] media: imx-media-csi: Fix inconsistent IS_ERR and PTR_ERR

  From: From: Gustavo A. R. Silva <gustavo@embeddedor.com>

Fix inconsistent IS_ERR and PTR_ERR in imx_csi_probe.
The proper pointer to be passed as argument is pinctrl
instead of priv->vdev.

This issue was detected with the help of Coccinelle.

Fixes: 52e17089d185 ("media: imx: Don't initialize vars that won't be used")

Hi Hans,

Unfortunately this one missed to be applied into 4.17-rc and now the
imx-media-csi driver does not probe.

Please consider applying it for 4.17-rc3 to avoid the regression.

Thanks
