1e00d57694 dm vdo logger: update logging to start with "device-mapper: vdo"
Stops short of actually using DM's various logging macros (e.g. DMERR,
DMINFO, etc) because VDO's logger isn't quite compatible with them.

Also switch emit_log_message_to_kernel() from open-coding printk with
log-level to using corresponding pr_ macro.

318a9ce59b 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().
