[PATCH] userns: eliminate many kernel-doc warnings

[Randy Dunlap]

Drop the kernel-doc "/**" notation from 8 structs or functions to
prevent 22 kernel-doc warnings  (samples below).

user_namespace.c:239: warning: Function parameter or member 'map_up' not described in 'idmap_key'
user_namespace.c:246: warning: Function parameter or member 'k' not described in 'cmp_map_id'
user_namespace.c:277: warning: Function parameter or member 'extents' not described in 'map_id_range_down_max'
user_namespace.c:295: warning: Function parameter or member 'extents' not described in 'map_id_range_down_base'
user_namespace.c:344: warning: Function parameter or member 'extents' not described in 'map_id_up_base'
user_namespace.c:364: warning: Function parameter or member 'extents' not described in 'map_id_up_max'
user_namespace.c:776: warning: Function parameter or member 'map' not described in 'insert_extent'
user_namespace.c:844: warning: Function parameter or member 'map' not described in 'sort_idmaps'

Fixes: 6397fac4915a ("userns: bump idmap limits to 340")
