Removed duplicated patch lines.

I was checking mmotm (2008-0527) kernel docs and got this error:

xmlto: input does not validate (status 3)
/local/linsrc/mmotm-2008-0527-0032/Documentation/DocBook/kernel-locking.xml:722: element chapter: validity error : ID trylock-functions already defined

Looks like Rusty's doc additions were duplicated.

- There are functions that try to acquire a lock only once and immediately
- return a value telling about success or failure to acquire the lock.
- They can be used if you need no access to the data protected with the lock
- when some other thread is holding the lock. You should acquire the lock
- later if you then need access to the data protected with the lock.
