block: make blk_init_free_list and elevator_init idempotent

Mike Snitzer authored 14 years ago


blk_init_allocated_queue_node may fail and the caller _could_ retry.
Accommodate the unlikely event that blk_init_allocated_queue_node is
called on an already initialized (possibly partially) request_queue.
