CloseDevice: call XkbRemoveResourceClient before freeing key class struct
This patch is not necessary at the current code level. But when xkb
code introduced the dev->key check Xorg upstream missed that. So we
backport it now to skip that trap when updating xkb code.

CloseDevice: call XkbRemoveResourceClient before freeing key class struct
XkbRemoveResourceClient() returns immediately if dev->key is NULL.
CloseDevice calls XkbRemoveResourceClient until it removes all resources.
If we free dev->key and NULL it before XkbRemoveResourceClient, then
infinite loop ensues, and the server appears to hang on exit or crash.
