[CIFS] when not using unix extensions, check for and set ATTR_READONLY on create and mkdir
When creating a directory on a CIFS share without POSIX extensions, and the given mode has no write bits set, set the ATTR_READONLY bit. When creating a file, set ATTR_READONLY if the create mode has no write bits set and we're not using unix extensions. There are some comments about this being problematic due to the VFS splitting creates into 2 parts. I'm not sure what that's actually talking about, but I'm assuming that it has something to do with how mknod is implemented. In the simple case where we have no unix extensions and we're just creating a regular file, there's no reason we can't set ATTR_READONLY.
