mm: fix pfn_t to page conversion in vm_insert_mixed
pfn_t_to_page() honors the flags in the pfn_t value to determine if a pfn is backed by a page. However, vm_insert_mixed() was originally written to use pfn_valid() to make this determination. To restore the old/correct behavior, ignore the pfn_t flags in the !pfn_t_devmap() case and fallback to trusting pfn_valid().
