patch 9.1.1528: completion: crash with getcompletion()

Problem:  completion: crash with getcompletion()
          (zeertzjq)
Solution: Don't set may_expand_pattern in f_getcompletion(),
          unset may_expand_pattern() once it is not longer needed
          (Girish Palya).

fixes: #17680
closes: #17686
