mm: introduce INIT_VMA()
Some VMA struct fields need to be initialized once the VMA structure is
allocated.
Currently this only concerns anon_vma_chain field but some other will be
added to support the speculative page fault.
Instead of spreading the initialization calls all over the code, let's
introduce a dedicated inline function.
