accel/tcg: Expand ATOMIC_MMU_LOOKUP_*
Unify the parameters of atomic_mmu_lookup between cputlb.c and user-exec.c. Call the function directly, and remove the macros. Tested-by: Cole Robinson <crobinso@redhat.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
