vim-patch:9.2.0081: Failed "z=" does not reset 'nospell' setting (#38109)

Problem:  When z= fails due to no word being found, 'spelllang' being
          unset or a multiline visual selection, 'nospell' is not
          restored.
Solution: Jump to where the user configured value of 'spell' is restored
          instead of returning early (Luuk van Baal).
