Bug fix dynamic menus

Dynamic menus had a buffer_len variable in the parent function but it
was discarded before passing to the callbacks

Why!!?? No clue but everything that used it was assuming MAXPATH
Wouldn't be surprised to see some bugs pop out from this one..

init_menu_lists() was assuming MENU_HAS_DESC and setting the
menu title + icon based on such even though it could be invalid
didn't see anywhere in the code that was currently using MENU_DYNAMIC_DESC
in relation to a top level menu but considering it caused all kinds
of corruption to the menu when I tried its probably been tried
and abandoned before...
