intel_iommu: Send IQE event when setting reserved bit in IQT_TAIL
According to VTD spec, Figure 11-22, Invalidation Queue Tail Register,
"When Descriptor Width (DW) field in Invalidation Queue Address Register
(IQA_REG) is Set (256-bit descriptors), hardware treats bit-4 as reserved
and a value of 1 in the bit will result in invalidation queue error."
Current code missed to send IQE event to guest, fix it.
Fixes: c0c1d351849b ("intel_iommu: add 256 bits qi_desc support")
