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

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

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

xhciallocstreaminfo() allocates stream context array for streaminfo ->streamctxarray with xhciallocstreamctx(). When some error occurs, streaminfo->streamctxarray is not released, which will lead to a memory leak.

We can fix it by releasing the streaminfo->streamctxarray with xhcifreestreamctx() on the error path to avoid the potential memory leak.
