Xi: reset the known properties at the end of the server generation.

Browse source 
Properties allocated through XIGetKnownProperty() aren't reset on the second
server generation but keep the old value. As a result, wrong Atoms are
supplied to the driver, resulting in potential data corruption or weird
error message.

Reproducible by running "xlsatom | grep FLOAT" twice on a plain X server.
The second X server generation won't have the FLOAT atom defined anymore,
despite the users of this atom not noticing any errors.
