718abcb69b78385123dd7a05a66a656af772d581 tries to disable UDS_ACCESS
being set. See the long comment introduced.
It did this by setting the value to -1 which doesn't achieve that
result.
-1 is a perfectly valid value that gets send to the client.
Having it set breaks anyone calling udsEntry.numberValue(UDS_ACCESS,
aLegitimateDefault) getting their default. Something used by kio-fuse.
