vim-patch:9.1.2116: crash when using 'tagfunc' (#37627)

Problem:  crash when using 'tagfunc' (Rodrigo Queipo)
Solution: Do not add the user_data to the 'info' dictionary when called
          for insert mode completion (the TAG_INS_COMP flag is set).
          Completion should not depend on the state of a previous tag
          jump. (Yasuhiro Matsumoto)

fixes:  vim/vim#19255
closes: vim/vim#19284
