[vim/vim] Use-after-free with ":wqall" and a running terminal job (after v9.2.0593) (PR #20423)

[h_east]

Problem:  Using ":wqall" with a running terminal buffer can free the
          buffer that is currently being iterated over in the buffer
          list, resulting in a use-after-free.
Solution: After stopping the job, check whether the buffer is still valid
          and restart the iteration from the first buffer if it was freed.
