register_blkdev() is called before pci_register_driver() in skd_init()
so unregister_blkdev() should be called after pci_unregister_driver()
in skd_exit(). Fix it.

Remove skd_flush_cmd structure and skd_flush_slab.
Remove skd_end_request wrapper around skd_end_request_blk.
Remove skd_requeue_request, use blk_requeue_request directly.
Cleanup some comments (remove "bio" info) and whitespace.

Just call the block functions directly, don't wrap them
in skd helpers. With only one queueing model enabled, there's
no point in doing that.
Also kill the ->start_time and ->bio from the skd_request_context,
we don't use those anymore.

The skd driver has a selectable rq or bio based queueing model.
For 3.14, we want to turn this into a single blk-mq interface
instead. With the immutable biovecs being merged in 3.13, the
bio model would need patches to even work. So rip it out, with
a conversion pending for blk-mq in the next release.

Fix to return -ENOMEM in the skd construct error handling
case instead of 0, as done elsewhere in this function.

This patch fixes checkpatch.pl errors for assignment in if condition.
It also removes unused readq / readl function calls.
As Andrew had disabled the compilation of drivers for 32 bit,
I have modified format specifiers in few VPRINTKs to avoid warnings
during 64 bit compilation.
