[PATCH v2 2/4] accel/tcg: Do not define cpu_exec_reset_hold() as stub

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

In commit 1b5120d74b ("accel: Introduce cpu_exec_reset_hold()")
we defined the user emulation backend cpu_exec_reset_hold() as
a stub. This was a mistake, since common fields are set in
CPU reset, and user emulation needs these fields to be resetted.
Move cpu_exec_reset_hold() back.
