mm: hugetlb: fix type of delta parameter and related local variables in gather_surplus_pages()
On 64-bit machine, delta variable in hugetlb_acct_memory() may be larger
than 0xffffffff, but gather_surplus_pages() can only use the low 32-bit
value now. So we need to fix type of delta parameter and related local
variables in gather_surplus_pages().
