When the daemon is started prior to udev the paths are not present
(yet). However, the maps themselves will be read from device-mapper.
This causes existing maps to be dropped in coalesce_maps(), only
to be reinstated later when all paths are discovered.
To avoid this we should be checking for a valid hardware entry
per multipath map; if there is none we're in startup and shouldn't
drop any maps.
