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

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

[ Upstream commit b114d9009d386276bfc3352289fc235781ae3353 ]

When LCB's are rejected, if beaconing was already in progress, the
Reason Code Explanation was not being set. Should have been set to
command in progress.
