[PATCH 5.8 003/232] SMB3: Fix mkdir when idsfromsid configured on mount

From: Greg Kroah-Hartman

From: Steve French <stfrench@xxxxxxxxxxxxx>

commit c8c412f976124d85b8ded85c6ac3f760c12b63a3 upstream.

mkdir uses a compounded create operation which was not setting
the security descriptor on create of a directory. Fix so
mkdir now sets the mode and owner info properly when idsfromsid
and modefromsid are configured on the mount.
