usb: cdnsp: fix stream context array leak in cdnsp_alloc_stream_info()

Browse Source 
commit 3348f444a4 upstream.

cdnsp_alloc_stream_info() allocates stream_info->stream_ctx_array with
cdnsp_alloc_stream_ctx(). If a later stream ring allocation or stream
mapping update fails, the error path frees the allocated stream rings
and stream_rings array, but leaves stream_ctx_array allocated.

Free the stream context array before falling through to the stream_rings
cleanup path.
