iommu/arm-smmu: fix races on domain->smmu
Clients are allowed to attach/detach and map/unmap independently. I.e.,
they don't have to be attached at the time they map or unmap. Currently
if they detach and unmap at the same time there's a race condition where
the SMMU associated with the domain could go away while we try to use
it. Fix this by locking the domain lock everywhere that domain->smmu is
used.
