vim-patch:9.1.1573: Memory leak when pressing Ctrl-D in cmdline mode

Problem:  Memory leak when pressing Ctrl-D in cmdline mode
          (after 9.1.1571).
Solution: Free prev_cmdbuff before assigning to it.
          (zeertzjq).

Existing tests already cover this. This change fixes the CI failure.

closes: vim/vim#17807
