ldd3: get rid of deprecated VM_RESERVED vma flag
commit 314e51b9 ("mm: kill vma flag VM_RESERVED and mm->reserved_vm counter")
removed the VM_RESERVED vma flag since it lost original meaning.
VM_RESERVED was used on many drivers' mmap function handler to
avoid swap this memory area.
The same semantic can be specified with VM_IO | VM_DONTDUMP flags
but these are already set by remap_pfn_range() so they don't have
to be set in drivers mmap function handlers.
