Most should be VDO_SUCCESS. But comparing the return from
kstrtouint() with UDS_SUCCESS (happens to be 0) makes no sense.

Also rename ASSERT to VDO_ASSERT and ASSERT_LOG_ONLY to
VDO_ASSERT_LOG_ONLY.
But re-introduce ASSERT and ASSERT_LOG_ONLY as a placeholder
for the benefit of dm-vdo/indexer.

Requires moving dm-vdo-target.c into drivers/md/dm-vdo/
This change adds a proper drivers/md/dm-vdo/Makefile and eliminates
the abnormal use of patsubst in drivers/md/Makefile -- which was the
cause of at least one build failure that was reported by the upstream
build bot.
Also, split out VDO's drivers/md/dm-vdo/Kconfig and include it from
drivers/md/Kconfig
