4.9-stable review patch. If anyone has any objections, please let me know.

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

From: Johan Hovold <johan@xxxxxxxxxx>

commit 63afd5cc78775018ea2dec4004428dafa5283e93 upstream.

Add missing endianness conversion when applying the Alea timeout quirk.

Found using sparse:

warning: restricted __le16 degrades to integer
