moving: fix the cursor jumping back and forth with non-smooth paging

Since commit 8490f4ac, get_edge_and_target() depends on an up-to-date
current_x.  So: make sure current_x is updated when we move to the
top left of the screen to start a non-smooth PageUp or PageDown.

This fixes https://savannah.gnu.org/bugs/?51480.
