skd: Convert to blk-mq
Introduce a tag set and a blk_mq_ops structure. Set .cmd_size such
that struct request and struct skd_request_context are allocated
through a single allocation. Remove the skd_request_context.req
pointer. Make queue starting asynchronous such that this can occur
safely from interrupt context. Use locking to protect skdev->skmsg
and *skdev->skmsg against concurrent access from concurrent
.queue_rq() calls. Introduce the functions skd_init_request() and
skd_exit_request() to set up / clean up the per-request S/G-list.
