Better to align page_entries to the open parenthesis.

And another optimization would be to simply add DB_PAGE_SIZE to tmp
in the loop and avoid the multiply.

		for (page_entries = 0;
		     page_entries < MAX_DB_PAGES_PER_BQ(QLGE_BQ_LEN);
		     page_entries++) {
			base_indirect_ptr[page_entries] = cpu_to_le64(tmp);
			tmp += DB_PAGE_SIZE;
		}
