[PATCH] dri2: Destroy buffer before reseting the private key

[Pauli]

From: Pauli Nieminen <ext-pauli.nieminen at nokia.com>

Destroying buffers after reseting the private key would prevent DDX
from calling DRI2 functions that require private.

This can be result to
[DRI2] DRI2SwapComplete: bad drawable
when drivers calls SwapCompletion in state clean up code.

Restriction can be avoided if destroy buffer hook is called before
private key clean up.
