accel/tcg/translate-all: expand cpu_restore_state addr check
We are still seeing signals during translation time when we walk over
a page protection boundary. This expands the check to ensure the host
PC is inside the code generation buffer. The original suggestion was
to check versus tcg_ctx.code_gen_ptr but as we now segment the
translation buffer we have to settle for just a general check for
being inside.
I've also fixed up the declaration to make it clear it can deal with
invalid addresses. A later patch will fix up the call sites.

Bug description:
Some of the recent changes introduced a regression which makes the
OpenJDK JVM crash on qemu-sh4:
(sid-sh4-sbuild)root@nofan:/# java -version
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
