Keith Packard 10d2805dbc fb: Don't free NULL pixmap in fbCloseScreen. Bug #80313 ...

We fixed fbCloseScreen to use the FreePixmap function so that the
private counts would be updated correctly during CloseScreen. Xvfb
calls FreePixmap and sets devPrivate to NULL before fbCloseScreen is
called; not checking devPrivate before calling would result in a NULL
pointer dereference.
