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.

Original code will reset the whole USB device when xHCI Reset
Endpoint command is received, this behavior is not right. This
patch is used to fix it.
And according to xhci spec 4.6.8, if the endpoint is not in the
halted state, xHC should reject to execute this command and the
Context State Error should be returned. This patch also add this
logic.

This patch correct the USB request type which set wrong direction in
original code. It caused these important usb control transfer packets
send to phsical USB devices via libusb_control_transfer instead of
calling standard libusb APIs, likes libusb_set_configuration. From
libusb document, this is not the correct way:
"You should always use this function rather than formulating your own
SET_CONFIGURATION control request. This is because the underlying
operating system needs to know when such changes happen."
