Roger Quadros 97e133d54c usb: gadget: core: fix ->udc_set_speed() logic
Consider the following case: udc controller supports SuperSpeed.  If we
first load a HighSpeed gadget followed by a SuperSpeed gadget, the
SuperSpeed gadget will be limited to HighSpeed as UDC core driver
doesn't call ->udc_set_speed() in the second case.

Call ->udc_set_speed() unconditionally to fix this issue.

This will also fix the case for dwc3 controller driver when SuperSpeed
gadget is loaded first and works in HighSpeed only as udc_set_speed()
was never being called.

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
