Do not lookup sysfs devices in cache for 'add' events

For 'add' events the same devpath might point to a different
device, so we really shouldn't lookup the device in the cache.
Rather we should omit the cache altogether and use a new one.
For any sane operation the stale device should have received
a 'remove' event, so the cache should've been cleaned up.
