Alexander Korotkov 6058900348 Fix checkpointer shared memory allocation 
Use Min(NBuffers, MAX_CHECKPOINT_REQUESTS) instead of NBuffers in
CheckpointerShmemSize() to match the actual array size limit set in
CheckpointerShmemInit().  This prevents wasting shared memory when
NBuffers > MAX_CHECKPOINT_REQUESTS.  Also, fix the comment.
