Re: [PATCH v2 14/15] qemu_validate: Check if QEMU's capable of setting main loop pool size

Since the main-loop and iothread classes are derived from the same class (EventLoopBaseClass) we don't need new capability and can use QEMU_CAPS_IOTHREAD_THREAD_POOL_MAX directly to check whether QEMU's capable of setting worker pool size.
