knav_queue_open always returns an ERR_PTR value, never NULL. This can be
confirmed by unfolding the function calls and conforms to the function's
documentation. Thus, replace IS_ERR_OR_NULL by IS_ERR in error checks.
The change is made using the following semantic patch:

// <smpl>
@@
expression x;
statement S;
@@
x = knav_queue_open(...);
if (
- IS_ERR_OR_NULL
+ IS_ERR
(x)) S
// </smpl>
