[PATCH] ACPI: Use LIST_HEAD() to initialize on stack list head

[Jisheng Zhang]

Use LIST_HEAD to initialize on stack list head. No intentional
functional impact.

Change generated with below coccinelle script:

@@
identifier name;

- struct list_head name;
+ LIST_HEAD(name);
... when != name
- INIT_LIST_HEAD(&name);
