Joonsoo Kim b136be5e0b mm, vmalloc: use well-defined find_last_bit() func ...

Our intention in here is to find last_bit within the region to flush.
There is well-defined function, find_last_bit() for this purpose and its
performance may be slightly better than current implementation.  So change
it.
