arm64: mm: Test for pmd_sect() in vmemmap_check_pmd()
Commit 2045a3b8911b ("mm/sparse-vmemmap: generalise vmemmap_populate_hugepages()") introduces the vmemmap_check_pmd() while does not verify if the entry is a section mapping, as is already done for Loongarch & X86. The update includes a check for pmd_sect(). Only if pmd_sect() returns true, further vmemmap population for the addr is skipped.
