[PATCH 4.19 95/96] net: bridge: explicitly zero is_sticky in fdb_create

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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

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

From: Nikolay Aleksandrov <nikolay@cumulusnetworks.com>

commit 1288aa7af20cfa25cb00cf0d77f94d1891644c83 upstream.

We need to explicitly zero is_sticky when creating a new fdb, otherwise
we might get a stale value for a new entry.

Fixes: 435f2e7cc0b7 ("net: bridge: add support for sticky fdb entries")
