[56/83] USB: keyspan: fix bogus array index

[Ben Hutchings]

3.2.47-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Johan Hovold <jhovold@xxxxxxxxx>

commit a07088098a650267b2eda689538133a324b9523f upstream.

The outcont_endpoints array was indexed using the port minor number
(which can be greater than the array size) rather than the device port
number.
