Required for ANY_LAYOUT support when the incoming virtio-scsi response

Move logic for typical vhost_scsi_handle_vq() -> tcm_vhost_workqueue ->
tcm_vhost_submission_work() dispatch into vhost_scsi_queue_desc().
Can be shared by vhost_scsi_handle_vqal() code.

This patch fixes vhost_scsi_handle_vq() failure cases that result in BUG_ON()

This patch changes vhost_scsi_map_to_sgl() parameters to accept virtio
iovec ptr + len when determing pages_nr.
This is currently done with iov_num_pages() -> PAGE_ALIGN, so allow
the same parameters as well.

Hi MST & Paolo,
The series adds initial vhost/scsi ANY_LAYOUT layout support.

This patch adds ANY_LAYOUT prerequisites logic for accepting a set of
protection + data payloads via iovec + offset. Also includes helpers
for calcuating SGLs + invoking vhost_scsi_map_to_sgl() with a known
number of iovecs.

The bug in this code is "if (err_warn_bit_map & (u64) (1 << i)) {".
The cast to u64 happens after we have already shift wrapped so it's too
late. Presumably this means some warnings are ignored.
I also cleanup the other err_warn_bit_map check.

"m_sg->baseaddr_h" is a u32. We shift it 32 bits before casting it to
dma_addr_t so the cast is too late.

The 'data_dir' variable is not used in sg_common_write(), hence

Currently when performing a reboot with an ipr adapter,
the adapter gets shutdown completely, flushing all write
cache, as well as performing a full hardware reset of the card
during the shutdown phase of the old kernel. This ensures
the adapter is in a fully quiesced state across the reboot.
