A later patch in this series fails the test pool because
scan-build says we might be using garbage for one of the
descriptor pointer comparisons. That later patch does not
touch this unit test file at all, and the bdev-related changes
do not touch the code path used around the bug report. But
the report is valid - it's possible that with the additional
bdev.c changes that scan-build's ability to detect this
bug changed for the better.

DPDK is now fully synchronized with the rest of vhost.
This patch also removes timed_event API from vhost_internal.h.
It should only be used internally in vhost.c under g_spdk_vhost_mutex.
Also, this patch temporarily gets rid of return codes for
vhost_scsi/blk dpdk callbacks. -1 will be returned if the
call timed out, 0 otherwise. A patch reenabling this
functionality is on the way

First, improve packing of spdk_bdev_io. Move any
fields which must be zeroed into the first cacheline.
Also change type and status from enums (needing 4 bytes)
to int16_t which is still a far bigger range than
needed.
Next, modify spdk_bdev_get_io to only zero the
first cacheline (actually a bit less).
SPDK_BDEV_IO_TYPE_INVALID is also added, making it
explicit that 0 is an invalid value for the IO type.
Previously this was somewhat inferred.
There are still additional improvements that can
be made to this area - primarily combining
spdk_bdev_get_io() and spdk_bdev_io_init() into
a single function.
