Add a new dmsetup message called config, which will return
useful configuration information for the vdo volume and

additions to the content.

Ignore scnprintf return status since it is not necessary. Change
write_* functions type from int to void since we no longer return
any result. Also, clean up any code that checks or uses any scnprintf
return results.
Check uds_allocate return code which was previous ignored, return
and log error when uds_allocate failed.
