block: switch numa_node to int in blk_mq_hw_ctx and init_request

numa_node in blk_mq_hw_ctx and the matching argument of
blk_mq_ops::init_request can be NUMA_NO_NODE (-1).  Declared as
unsigned int, NUMA_NO_NODE becomes UINT_MAX and walks off
nvme_dev::descriptor_pools[] on CONFIG_NUMA=n [1].

Switch the field and the callback prototype to int and update all
in-tree init_request implementations.  No functional change:
cpu_to_node(), kmalloc_node() and blk_alloc_flush_queue() already
take int.
