Todd Kjos db6b0b810b binder: avoid kernel vm_area for buffer fixups
Refactor the functions to validate and fixup struct
binder_buffer pointer objects to avoid using vm_area
pointers. Instead copy to/from kernel space using
binder_alloc_copy_to_buffer() and
binder_alloc_copy_from_buffer(). The following
functions were refactored:

	refactor binder_validate_ptr()
	binder_validate_fixup()
	binder_fixup_parent()
