fix SBA IOMMU to handle allocation failure properly
commit e2a465675dc089e9a56ba2fa2a5fbd9bd8844d18 upstream.
It's possible that SBA IOMMU might fail to find I/O space under heavy
I/Os. SBA IOMMU panics on allocation failure but it shouldn't; drivers
can handle the failure. The majority of other IOMMU drivers don't panic
on allocation failure.
This patch fixes SBA IOMMU path to handle allocation failure properly.
