dm vdo logger: switch UDS_LOG_NOTICE to be alias for UDS_LOG_INFO

Prepare to bring VDO's logging closer to DM's logging by eliminating
support for KERN_NOTICE log level (DM hasn't ever had a need for it).

Only one message in index-session.c used UDS_LOG_NOTICE, convert it to
log with uds_log_info().
