[media] drivers/media/platform/mx2_emmaprp.c: adjust inconsistent IS_ERR and PTR_ERR

Author: Julia Lawall <Julia.Lawall@lip6.fr>

Change the call to IS_ERR to test the value that was just initialized and
is returned using PTR_ERR.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// 
@@
expression e,e1;
@@

(
if (IS_ERR(e)) { ... PTR_ERR(e) ... }
|
if (IS_ERR(e=e1)) { ... PTR_ERR(e) ... }
|
*if (IS_ERR(e))
 { ...
*  PTR_ERR(e1)
   ... }
)
//
