usb-host: add usb_host_do_reset function.
Add a special function to reset the host usb device. It tracks the time
needed by the USBDEVFS_RESET ioctl and prints a warning in case it needs
too long. Usually it should be finished in 200 - 300 miliseconds.
Warning threshold is one second.
Intention is to help troubleshooting by indicating that the usb device
stopped responding even to a reset request and is possibly broken.
