ehci: update irq on reset
After clearing the status register we also have to update the irq line status. Otherwise a irq which happends to be pending at reset time causes a interrupt storm. And the guest can't stop as the status register doesn't indicate any pending interrupt. Both NetBSD and FreeBSD hang on shutdown because of that.
