[patch 35/47] use LIST_HEAD instead of LIST_HEAD_INIT

[Martin Schwidefsky <schwidefsky@de.ibm.com>]

From: Denis Cheng <crquan@gmail.com>

single list_head variable initialized with LIST_HEAD_INIT could almost
always can be replaced with LIST_HEAD declaration, this shrinks the code
and looks better.
