Subject: [PATCH 4.8 089/138] rtl8xxxu: Fix big-endian problem reporting mactime

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

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

From: Jes Sorensen <Jes.Sorensen@...hat.com>

commit 8a55698f2f29d227825173420d7b99b9277ca88c upstream.

The full RX descriptor is converted so converting tsfl again would
return it to it's original endian value.
