[PATCH -next] [media] siano: use DEFINE_MUTEX() for mutex lock and LIST_HEAD for list head

[Ye Bin <yebin10@xxxxxxxxxx>]

mutex lock can be initialized automatically with DEFINE_MUTEX()
rather than explicitly calling mutex_init().
list head can be initialized automatically with LIST_HEAD()
rather than explicitly calling INIT_LIST_HEAD().
