usb: host: xhci: Fix potential memory leak in xhci_alloc_stream_info()

In the Linux kernel, the following vulnerability has been resolved:

usb: host: xhci: Fix potential memory leak in xhci_alloc_stream_info()

xhci_alloc_stream_info() allocates stream context array for stream_info
->stream_ctx_array with xhci_alloc_stream_ctx(). When some error occurs,
stream_info->stream_ctx_array is not released, which will lead to a
memory leak.

We can fix it by releasing the stream_info->stream_ctx_array with
xhci_free_stream_ctx() on the error path to avoid the potential memory
leak.

CWE-401 Missing Release of Memory after Effective Lifetime

The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory.
