    gnttab: don't cast away constness
    
    While _set_status_v2() indeed doesn't alter the grant_entry_header_t it
    is handed a pointer to, _set_status_v1() does. Drop the const from the
    parameter of the latter (and then necessarily also from _set_status()'s),
    while adding const to the local variable of the former.
    
    No functional change.
