usb: gadget: function: f_obex: fix Interface Descriptor Test
On USB20CV's Interface Descriptor Test, a series
of SetInterface/GetInterface requests are issued
and gadget driver is required to always return
correct alternate setting.
In one step of the test, g_serial with f_obex
was returning the wrong value (1 instead of 0).
In order to fix this, we will now hold currently
selected alternate setting inside our struct f_obex
and just return that from our ->get_alt()
implementation.
Note that his also simplifies the code a bit.
