mod_http_muc_log: Remove dead code
This might be something left over since a different variant where the
loop went like `for n = i-1, i-100, -1 do ... end` i.e. it went trough a
fixed number of items instead of all the page until the current message.
Then it would have needed something to stop going over the end, but
since the checks are simple it shouldn't be much of a problem looping
over even a very busy day.
