Subject: drm/ast: Init cursors before creating modesetting structures
Git-commit: 6bb18c9be6d256d7e8e24e7a676df2e2fd72522c
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
The cursor helpers reserve buffer objects in VRAM and update their
content. So although tied to modesetting, cursor helpers are more
of a memory manager. The modesetting's cursor plane requires this
functionality, so initialize cursors before modesetting.
While at it, also add an error check for ast_cursor_init().
