xlib: clear currentDpy when releasing the current context

Browse source 
After abe6d750e5, glXDestroyContext() can defer destruction by marking
the context with xid == None while it is still current.

However, the release-current path did not clear current->currentDpy,
so a context that had already been marked for deletion could remain
associated with a display after unbinding.

Fixes: abe6d750e5 ("xlib: fix glXDestroyContext in Gallium frontends")
