drm/fb-helper: Fix a locking bug in an error path
The name of the function __drm_fb_helper_initial_config_and_unlock() and
also the comment above that function make it clear that all code paths
in this function should unlock fb_helper->lock before returning. Add a
mutex_unlock() call in the only code path where it is missing. This has
been detected by the Clang thread-safety analyzer.
