[PATCH] media: bcm2835-unicam: Fix a NULL vs IS_ERR() check

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

The media_pad_remote_pad_unique() function returns error pointers, not
NULL.  Update the check accordingly.

Fixes: 392cd78d495f ("media: bcm2835-unicam: Add support for CCP2/CSI2 camera interface")
