Subject: [PATCH] diaryreqs: Update scrollbar with new length

This interface was ported to a different widget (in #5346), but that interface has a dynamic length, controlled by cs2 2523, which is called by the server when the interface is filled. Simply call the cs2 again after the next one has ran with our new linecount.
