Description: Fix vboxvideo guest additions build on Linux kernel 7.0+
 Linux kernel 7.0 removed the fb_debug_enter and fb_debug_leave members
 from struct fb_ops. This patch conditionally excludes these initializations
 using the RTLNX_VER_MAX macro to prevent compilation failures and subsequent
 system boot hangs during VirtualBox guest additions installation.
