[PATCH net-next v2] ionic: Change list definition method

[Lei Zhu <zhulei_szu@163.com>]

From: Lei Zhu <zhulei@kylinos.cn>

The LIST_HEAD macro can both define a linked list and initialize
it in one step. To simplify code, we replace the separate operations
of linked list definition and manual initialization with the LIST_HEAD
macro.

Changes in v2:
  - Order the variable declaration lines longest to shortest
