    xsm: Drop extern of non-existent variable
    
    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")
