Hongbo Li 27a8204b26 vfio/mdev: Constify struct kobj_type 
This 'struct kobj_type' is not modified. It is only used in
kobject_init_and_add() which takes a 'const struct kobj_type *ktype'
parameter.

Constifying this structure and moving it to a read-only section,
and this can increase over all security.
