kernel-doc: restrict syntax for private: and public:

Browse source 
scripts/kernel-doc can (incorrectly) delete struct members that are
surrounded by /* ...  */ <struct members> /* ...  */ if there is a /*
private: */ comment in there somewhere also.

Fix that by making the "/* private:" only allow whitespace between /* and
"private:", not anything/everything in the world.

This fixes some erroneous kernel-doc warnings that popped up while
processing include/linux/usb/composite.h.
