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.
