[PATCH] test/py: Have test_usb.py raise an Exception with unsupported filesystems

[Tom Rini]

With a newer pylint we get a warning about how offset could be used
before assigned. This is because when the underlying filesystem wasn't
one that is supported we would have runtime test failures. Address this
by raise'ing an Exception if fs is not supported.
