ublk: rewrite ublk_ctrl_get_queue_affinity to not rely on hctx->cpumask
Looking at the hctxs and cpumap is not safe without at very last a RCU
reference. It also requires the queue to be set up before starting the
device, which leads to rather awkward life time rules.
Instead rewrite ublk_ctrl_get_queue_affinity to just build the cpumask
directly from the mq_map in the tag set, similar to hctx->cpumask is
built.
