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.
