Subject: [PATCH 4.4 35/40] cifs: In Kconfig CONFIG_CIFS_POSIX needs depends on legacy (insecure cifs)

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

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

[ Upstream commit 6e785302dad32228819d8066e5376acd15d0e6ba ]

Missing a dependency.  Shouldn't show cifs posix extensions
in Kconfig if CONFIG_CIFS_ALLOW_INSECURE_DIALECTS (ie SMB1
protocol) is disabled.
