libview: only access the relevant page cache for the height request
In ev_view_get_height_to_page, the "height" or "dual_height" pointer can be set. If dual_height is set, the dual_height buffer is used. Using the "normal" height cache in dual view causes an out of bounds read. So we restrict the cache accesses to their relevant buffers. https://bugzilla.gnome.org/show_bug.cgi?id=771612 origin commit: https://git.gnome.org/browse/evince/commit/?id=0d44134
