accel/tcg: Simplify tlb_plugin_lookup
Now that we defer address space update and tlb_flush until the next async_run_on_cpu, the plugin run at the end of the instruction no longer has to contend with a flushed tlb. Therefore, delete SavedIOTLB entirely. Properly return false from tlb_plugin_lookup when we do not have a tlb match. Fixes a bug in which SavedIOTLB had stale data, because there were multiple i/o accesses within a single insn. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
