virtio_blk - Clean up some unneeded functionalities.
* Get rid of remaining code for handling the B_ORDERED flag.
B_ORDERED doesn't even exist anymore in DragonFly.
* Get rid of sc->vtblk_req_ready request list. We can just use
bioqdisksort() to add a request - that we failed to enqueue ino the
virtqueue - back into the bioq.
* Rename req->vbr_bp field to req->vbr_bio.
* Switch vtblk_req_free list from TAILQ to SLIST. A small optimization,
none of the additional features of the TAILQ are needed here.

virtio - Fix a few porting issues and bugs
* vtblk_maximum_segments() was really buggy. It was
adding the base min segments to blkcfg->seg_max,
miscalculating values for the case where the F_SEG_MAX
feature is not in the feature list.
This could result in virtio imploding on a too-small
sglist.
* Fix situations where M_NOWAIT is improperly used.
* At least use 16-byte alignment for contigmalloc()'s.
