[PATCH] rust/drm/gem: initialize callbacks with ..pin_init::zeroed()

[Klara Modin]

When the commit b67d2d039f64 ("drm/gem: Add callback for when handle
count goes to 0") added the handle_free callback, it did not update the
rust abstraction, which will cause a build failure when that is enabled.
Rather than just adding another None initializer, use
..pin_init::zeroed() to make all unlisted callbacks None, and remove the
existing None-initializations.

Fixes: b67d2d039f64 ("drm/gem: Add callback for when handle count goes to 0")
