Guenter Roeck ca263dd848 mei: Drop unnecessary NULL check after container_of 
The result of container_of() operations is never NULL unless the embedded
element is the first element of the data structure, which is not the case
here. The NULL check is therefore unnecessary and misleading. Remove it.

This change was made automatically with the following Coccinelle script.

@@
type t;
identifier v;
statement s;
@@

<+...
(
  t v = container_of(...);
|
  v = container_of(...);
)
  ...
  when != v
- if (\( !v \| v == NULL \) ) s
...+>
