[PATCH 2/2] of: unittest: Remove bogus overlay mutex release from overlay_data_add()

[Geert Uytterhoeven]

overlay_data_add() never takes the special overlay mutex, so it must not
be released in the error patch.

Presumably the call to of_overlay_mutex_unlock() is a relic from v1 of
the patch.

Fixes: f948d6d8b792bb90 ("of: overlay: avoid race condition between applying 
multiple overlays")
