For AMD machine with SME feature, makedumpfile tools need to know
whether the crash kernel was encrypted or not. If SME is enabled
in the first kernel, the crash kernel's page table(pgd/pud/pmd/pte)
contains the memory encryption mask, so need to remove the sme mask
to obtain the true physical addr
