x86/mm: Use l1e_get_pfn() in destroy_grant_pte_mapping().

On x86_64 system, (pte >> PAGE_SHIFT) is not always equal to page
frame number because high bits (63:52) of pte may be used as
flags. This patch corrects the conversion and errors as below
disappear when applied.
    (XEN) mm.c:3074:d0 PTE entry 200000a2ec6167 for address a1f09958
    doesn't match frame a2ec6
