Weinan Liu 10161b4a79 iommu/amd: Fix precedence order in set_dte_passthrough() 
Bitwise OR | operator has a higher precedence than the ternary ?:
operatior. It will be incorrectly evaluated as:

new->data[1] |= (FIELD_PREP(...) | dev_data->ats_enabled) ? DTE_FLAG_IOTLB : 0;

Wrap the conditional operation in parentheses to enforce the
correct evaluation order.
