UPSTREAM: wifi: mac80211_hwsim: set virtio device ready in probe()

Browse Source 
Just like a similar commit to arch/um/drivers/virt-pci.c, call
virtio_device_ready() to make this driver work after commit
b4ec69d7e09 ("virtio: harden vring IRQ"), since the driver uses
the virtqueues in the probe function.  (The virtio core sets
the device ready when probe returns.)

Bug: 254441685
Fixes: 8b4ec69d7e09 ("virtio: harden vring IRQ")
Fixes: 5d44fe7c9808 ("mac80211_hwsim: add frame transmission support over virtio")
