The USB device subsystem driver's set_interface() function calls
usb_dc_ep_configure() followed by usb_dc_ep_enable(). When
switching between alternate settings of a configuration's
interface, set_endpoint() can be followed by reset_endpoint() on
an endpoint. Some time later, set_endpoint() can be called again
on the same endpoint. This results in the HAL's
kUSB_DeviceControlEndpointInit function being called twice in a
row, which causes a memory allocation error. A simple solution is
to call the HAL's kUSB_DeviceControlEndpointDeinit function
before calling kUSB_DeviceControlEndpointInit. This overcomes the
memory allocation error.
