The per device io_lock became a coarser grained lock after multi-queues/rings

The max number of hardware queues for xen/blkfront is set by parameter
'max_queues', while the number xen/blkback supported is notified through
xenstore("multi-queue-max-queues").
The negotiated number was the smaller one, and was written back to
xen/blkback as "multi-queue-num-queues".

Split per ring information to an new structure:blkfront_ring_info, also rename
per blkfront_info to blkfront_dev_info.
A ring is the representation of a hardware queue, every vbd device can associate
with one or more blkfront_ring_info depending on how many hardware
queues/rings to be used.

Only one hardware queue is used now, so there is no significant
performance change

drivers like virtio, mtip, and nvme

Prepare patch for multi hardware queues/rings, the ring number was set to 1 by

* Use 'nr_rings' in per dev_info to identify how many hw queues/rings are
supported, and a pointer *rinfo for all its rings.
* Rename 'nr_ring_pages' => 'pages_per_ring' to distinguish from 'nr_rings'
better.
The CPU_DEAD_FROZEN state is abused to report to cpu_wait_death() that
the operation timeout. It has nothing to do with the pm freezing
process. Introduce a new state to allow proper distinction between the
states and also prepares the code to get rid of all FROZEN states.
