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.

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

"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 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.

This patch adds a new memcpy_fromiovec_out() library function which modifies
the passed *iov following memcpy_fromiovec(), but also returns the next current

Move logic for typical vhost_scsi_handle_vq() -> tcm_vhost_workqueue ->
