End address of the vm area is .start + bytes -1., not start + byte.
This patch fixes that issue by doing an inclusive comparison with
tmp->da_start. This issue was preventing allocate an area of size
exactly the same than the free area. I did no change the value of
da_end of each vm area because it is used to get area size in
several places.
