radix-tree: add/correct some kernel-doc

Correct some kernel-doc issues in radix-tree.h:
- use "DOC:" so that a kernel-doc comment is parsed correctly
  (or we could just use "/*" for that comment)
- add one function parameter description
- add one function parameter name inside the prototype

to fix these warnings:

Warning: include/linux/radix-tree.h:164 Incorrect use of kernel-doc format:
 * radix_tree_deref_slot - dereference a slot
Warning: include/linux/radix-tree.h:177 cannot understand function
 prototype: '* @slot: slot pointer, returned by radix_tree_lookup_slot
Warning: include/linux/radix-tree.h:192 function parameter 'treelock'
 not described in 'radix_tree_deref_slot_protected'
Warning: include/linux/radix-tree.h:309 function parameter '' not
 described in 'radix_tree_next_chunk'
