swiotlb: remove unused fields in io_tlb_mem
Commit 20347fca71a3 ("swiotlb: split up the global swiotlb lock") splits io_tlb_mem into multiple areas. Each area has its own lock and index. The global ones are not used so remove them. Signed-off-by: Chao Gao <chao.gao@intel.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
