iommu/arm-smmu-v3: disable stall for quiet_cd
In the stall model, invalid transactions were expected to be
stalled and aborted by the IOPF handler.
However, when killing a test case with a huge amount of data, the
accelerator streamline can not stop until all data is consumed
even if the page fault handler reports errors. As a result, the
kill may take a long time, about 10 seconds with numerous iopf
interrupts.
So disable stall for quiet_cd in the non-force stall model, since
force stall model (STALL_MODEL==0b10) requires CD.S must be 1.
