From: Max Gurtovoy <maxg@mellanox.com>
Iommu iotlb can be accessed by different cores for performing IO using
multiple virt queues. Add a spinlock to synchronize iotlb accesses.
This could be easily reproduced when using more than 1 pktgen threads
to inject traffic to vdpa simulator.
Fixes: 2c53d0f64c06f("vdpasim: vDPA device simulator")

The patch tries to fix a bug which is a commit introduced in 5.4.
So I think backporting it to 5.4 stable should be sufficient.
