Subject: [PATCH] zink: Fix crash on zink_create_screen error path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The `zink_internal_create_screen()` function can fail before
`screen->loader_lib` and/or `screen->instance` are initialized.
The `zink_destroy_screen()` doesn't check those cases and crashes.
The error was found by Fedora's CI. The back trace is available at [1].

Fixes: 0c2045553fe4 ("zink: use screen destructor for creation fails")
