usbip: fix stub_rx: get_pipe() to validate endpoint number
commit 635f545a7e8be7596b9b2b6a43cab6bbd5a88e43 upstream.
get_pipe() routine doesn't validate the input endpoint number
and uses to reference ep_in and ep_out arrays. Invalid endpoint
number can trigger BUG(). Range check the epnum and returning
error instead of calling BUG().
Change caller stub_recv_cmd_submit() to handle the get_pipe()
error return.
