Subject[PATCH 3.2 192/200] cifs: set MAY_SIGN when sec=krb5
3.2.56-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Martijn de Gouw <martijn.de.gouw@prodrive.nl>

commit 0b7bc84000d71f3647ca33ab1bf5bd928535c846 upstream.

Setting this secFlg allows usage of dfs where some servers require
signing and others don't.
