[PATCH] tools: usb: p9_fwd: wrap USBG shell command examples in literal code blocks

[Bagas Sanjaya]

Stephen Rothwell reported htmldocs warning when merging usb tree:

Documentation/filesystems/9p.rst:99: ERROR: Unexpected indentation.

That's because Sphinx tries rendering p9_fwd.py output as a grid table
instead.

Wrap shell commands in "USBG Example" section in literal code blocks
to fix above warning and to be in line with rest of commands in the doc.
