btl/vader: fix fragment sizes used by free lists

Просмотр исходного кода 
This commit fixes a bug introduced in
f62d26ddbc8cda4d985cceee531a2ec32406d1f6. That commit changed how
vader allocates fragment memory from the shared memory
segment. Unfortunately, the values used for the fragment sizes did not
include space for the fragment header. This can cause an overrun of
data from one fragment to the header of the next fragment.
