drm/ast: Fix connector leak during driver unload 



[ Upstream commit e594a5e349ddbfdaca1951bb3f8d72f3f1660d73 ]

When unloading the ast driver, a warning message is printed by
drm_mode_config_cleanup() because a reference is still held to one of
the drm_connector structs.

Correct this by calling drm_crtc_force_disable_all() in
ast_fbdev_destroy().
