Prevent redisplay slowdown with non-zero vscroll

* src/xdisp.c (try_scrolling): Don't loop when the
partially-visible cursor line is at the top of the window.  This
looping are pointless, and just makes redisplay slow for no reason.
(Bug#78766)

(cherry picked from commit 06b74b04cb86be6847bbee11e0060bf51c4a9ab5)
