Also update target major version number.

All info is (or will be) accessible through alternative interfaces
(e.g. "dmsetup message", module params, etc).

86492a3f69 dm vdo: slight cleanup of UDS error codes
No need to increment each UDS_ error code manually (relative to
UDS_ERROR_CODE_BASE).

Also, remove unused PRP_BLOCK_START and PRP_BLOCK_END.

Lastly, UDS_SUCCESS and VDO_SUCCESS are used interchangeably; so best
to explicitly set VDO_SUCCESS equal to UDS_SUCCESS.
