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

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

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.
