Xiaoguang Wu d6cc701c89 DM USB: refine logic of toggling interface state ...

Refine the logic of usb interface state transition.

The libusb uses two pair of APIs to deal with usb interface:
1. libusb_claim_interface & libusb_detach_kernel_driver;
2. libusb_release_interface & libusb_attach_kernel_driver.

The calling sequences of those APIs are very important, so this
patch add some error handling code to make this process more
robust.
