block: avoid unconditionally freeing previously allocated request_queue
On blk_init_allocated_queue_node failure, only free the request_queue if
it is wasn't previously allocated outside the block layer
(e.g. blk_init_queue_node was blk_init_allocated_queue_node caller).
This addresses an interface bug introduced by the following commit:
01effb0 block: allow initialization of previously allocated
request_queue
Otherwise the request_queue may be free'd out from underneath a caller
that is managing the request_queue directly (e.g. caller uses
blk_alloc_queue + blk_init_allocated_queue_node).
