    xsm: allow relevant permission during migrate and gpu-passthrough.
    
    During guest migrate allow permission to prevent
    spurious page faults.
    Prevents these errors:
    d73: Non-privileged (73) attempt to map I/O space 00000000
    
    avc: denied  { set_misc_info } for domid=0 target=11
    scontext=system_u:system_r:dom0_t
    tcontext=system_u:system_r:domU_t tclass=domain
    
    GPU passthrough for hvm guest:
    avc:  denied  { send_irq } for domid=0 target=10
    scontext=system_u:system_r:dom0_t
    tcontext=system_u:system_r:domU_t tclass=hvm
