linux-4.14.94: Remove CONFIG_CIFS_POSIX

CONFIG_CIFS_POSIX now depends on CIFS_ALLOW_INSECURE_LEGACY:

    commit ab9697222a1da17b6a4e909fab554b6ae5691789

    Date:   Sat Nov 3 15:02:44 2018 -0500

    cifs: In Kconfig CONFIG_CIFS_POSIX needs depends on legacy (insecure cifs)

    [ 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.

Remove CONFIG_CIFS_POSIX.
