nec-usb-xhci: set the device state to USB_STATE_DEFAULT
This patch is a rough fix to "hw/usb/core.c:401: usb_handle_packet:
Assertion `dev->state == 3' failed.". Qemu will crash when a usb3
device redirect to Windows7 VM via nec-usb-xhci.
In extensible-host-controler-interface-usb-xhci.pdf P94(4.6.5
Address Device):
• If the Block Set Address Request (BSR) flag = ‘1’
• If the slot is in the Enabled state:
...
• Set the Slot State in the Output Slot Context to Default.
BSR = ‘1’: Enabled state to Default state; BSR = ‘0’: Default state
to Addressed state. Try to call usb_device_reset to set device state
to USB_STATE_DEFAULT in xhci_address_slot wether bsr is zero.
