batman-adv: Utilize prandom_u32_max for random [0, max) values
The kernel provides a function to create random values from 0 - (max-1) since commit f337db64af05 ("random32: add prandom_u32_max and convert open coded users"). Simply use this function to replace code sections which use prandom_u32 and a handcrafted method to map it to the correct range. Signed-off-by: Sven Eckelmann <sven@narfation.org>
