[PATCH 4/8] accel/tcg: Fix append_mem_cb

["Alex Bennée" <alex.bennee@linaro.org>]

From: Richard Henderson <richard.henderson@linaro.org>

In fcdab382c8b9 we removed a tcg_gen_extu_tl_i64 from gen_empty_mem_cb,
and failed to adjust the associated copy, leading to a failed assert.

Fixes: fcdab382c8b9 ("accel/tcg: Widen plugin_gen_empty_mem_callback to i64")
