mm: hugetlb_vmemmap: replace early_param() with core_param() 

After the following commit:

  78f39084b4 ("mm: hugetlb_vmemmap: add hugetlb_optimize_vmemmap sysctl")

There is no order requirement between the parameter of
"hugetlb_free_vmemmap" and "hugepages" since we have removed the check of
whether HVO is enabled from hugetlb_vmemmap_init().  Therefore we can
safely replace early_param() with core_param() to simplify the code.
