scripts: kernel-doc: validate kernel-doc markup with the actual names

Kernel-doc currently expects that the kernel-doc markup to come
just before the function/enum/struct/union/typedef prototype.

Yet, if it find things like:

	/**
	 * refcount_add - add a value to a refcount
	 * @i: the value to add to the refcount
	 * @r: the refcount
	 */
	static inline void __refcount_add(int i, refcount_t *r, int *oldp);
	static inline void refcount_add(int i, refcount_t *r);

Kernel-doc will do the wrong thing:

	foobar.h:6: warning: Function parameter or member 'oldp' not described in '__refcount_add'
	.. c:function:: void __refcount_add (int i, refcount_t *r, int *oldp)

	   add a value to a refcount

	**Parameters**

	``int i``
	  the value to add to the refcount

	``refcount_t *r``
	  the refcount

	``int *oldp``
	  *undescribed*

Basically, it will document "__refcount_add" with the kernel-doc
markup for refcount_add.

If both functions have the same arguments, this won't even
produce any warning!

Add a logic to check if the kernel-doc identifier matches the actual
name of the C function or data structure that will be documented.
