[PATCH] dix: Fix a double free in dixFreePrivates.

[Francisco Jerez]

It can be reproduced when the server is regenerated and for some
reason the private keys are reassigned in a different order: a
manually allocated private may get an index formerly used by a
preallocated private. In that case it will first be manually freed and
then again by dixFreePrivates, as items[i].size was never zeroed
out. Do it in dixResetPrivates.
