[PATCH 4/5] accel/tcg: Have tcg_exec_realizefn() return a boolean

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Following the example documented since commit e3fe3988d7 ("error:
Document Error API usage rules"), have tcg_exec_realizefn() return
a boolean indicating whether an error is set or not.
