This should have been done at the point xsm_ops became fully altcall'd. This
puts the xsm_ops structure in .init on architectures where it is no longer
referenced at runtime.
Fixes: d868feb95a8a ("xen/xsm: Complete altcall conversion of xsm interface")

dummy_xsm_ops was dropped as part of organising XSM to be altcall compatible,
but the extern was accidentally left around.
A later change reintroduced dummy_ops which is logically the same thing, but
is private to xsm/dummy.c
Fixes: 164a0b9653f4 ("xsm: refactor xsm_ops handling")
