The vzalloc_node(), already rounds the total size to whole pages, and
sizeof(u64) is smaller than sizeof(struct recv_comp_data). So
round_up of recv_completion_cnt is not necessary, and may cause extra
memory allocation.

To save memory, remove this unnecessary round_up for recv_completion_cnt.

Applied, thanks.
