Fix assertion violation in DllMain of win32_threads

DllMain(DLL_THREAD_ATTACH) might be called for C runtime threads
before main() is launched, so this commit just removes wrong
assertion in DllMain.

* win32_threads.c [!GC_NO_THREADS_DISCOVERY] (GC_DllMain): Remove
entry_count static variable; remove assertion for entry_count and
parallel_initialized values in DLL_THREAD_ATTACH case.
