patch 9.2.0232: fileinfo not shown after :bd of last listed buffer

Problem:  fileinfo not shown after :bd of last listed buffer
          (memeplex)
Solution: Set need_fileinfo to true in empty_curbuf()
          (Hirohito Higashi)

When deleting the last listed buffer with :bd, the new empty buffer's
file info (e.g. "[No Name]" --No lines in buffer--) was not displayed.
do_ecmd() only calls fileinfo() for existing buffers (oldbuf), not for
newly created empty buffers.

Set need_fileinfo in empty_curbuf() so the file info is displayed after
redraw.

fixes:  #548
closes: #19802
