[PATCH] media: staging/imx: Checking the right variable in vdic_get_ipu_resources()

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

We recently changed this error handling around but missed this error
pointer check.  We're testing "priv->vdi_in_ch_n" instead of "ch" so the
error handling can't be triggered.

Fixes: 0b2e9e7947e7 ("media: staging/imx: remove confusing IS_ERR_OR_NULL usage")
