hw/riscv/riscv-iommu: Remove redundant struct members

Initially, the IOMMU would create a thread, but this thread was removed in
the merged version. The struct members for thread control should have been
removed as well, but they were not removed in commit 0c54acb8243
("hw/riscv: add RISC-V IOMMU base emulation").
