Erkki Seppälä f985a7319e mi/misprite: use memory management provided by dixRegisterPrivateKey ...

The record allocated by miSpriteDeviceCursorInitialize was not being
released.

This patch makes misprite use dixRegisterPrivateKey with the record
size argument, which handles the memory management issues.
miSpriteDeviceCursorInitialize is restructured to initialize pCursorInfo
only if miDCDeviceInitialize succeeds. The record itself is zeroed on
cleanup to ensure that the assumptions in the code still hold.
