[PATCH] nstree: fix func. parameter kernel-doc warnings

[Randy Dunlap]

Use the correct parameter name ("__ns") for function parameter kernel-doc
to avoid 3 warnings:

Warning: include/linux/nstree.h:68 function parameter '__ns' not described in 'ns_tree_add_raw'
Warning: include/linux/nstree.h:77 function parameter '__ns' not described in 'ns_tree_add'
Warning: include/linux/nstree.h:88 function parameter '__ns' not described in 'ns_tree_remove'
