KVM: Initialize irqfd waitqueue callback when adding to the queue

Initialize the irqfd waitqueue callback immediately prior to inserting the
irqfd into the eventfd's waitqueue.  Pre-initializing the state in a
completely different context is all kinds of confusing, and incorrectly
suggests that the waitqueue function needs to be initialize prior to
vfs_poll().
