vim-patch:8.2.0911: crash when opening a buffer for the cmdline window fails

Browse Source 
Problem:    Crash when opening a buffer for the cmdline window fails. (Chris
            Barber)
Solution:   Check do_ecmd() succeeds.  Reset got_int if "q" was used at the
            more prompt. (closes vim/vim#6211)
9b7cce28d5

Make code match latest Vim instead.
