mm: rmap: simplify the hugetlb handling when unmapping or migration
According to previous discussion [1], there are so many levels of
indenting to handle the hugetlb case when unmapping or migration. We can
combine folio_test_anon() and huge_pmd_unshare() to save one level of
indenting, by adding a local variable and moving the VM_BUG_ON() a little
forward.
No intended functional changes in this patch.
