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

[ Upstream commit f908c64650b455f09d0d2ada7417325b43d21f94 ]

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.
