vim-patch:8.2.2231: when "--remote file" is used "file" is not reloaded

Problem:    When "--remote file" is used "file" is not reloaded.
Solution:   When a :drop command is used for a file that is already displayed
            in a window and it has not been changed, check if it needs to be
            reloaded. (closes vim/vim#7560)

Remove unused "focus" parameter from "buf_check_timestamp()".
It was meant for removed GUI code.
