[PATCH] [media] media: am437x-vpfe: ensure ret is initialized

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

ret should be initialized to 0; for example if pfe->fmt.fmt.pix.field
is V4L2_FIELD_NONE then ret will contain garbage from the
uninitialized state causing garbage to be returned if it is non-zero.
