[PATCH v2] VFS: namei: fix start_dirop() kernel-doc warnings

[Randy Dunlap <rdunlap@infradead.org>]

Move the kernel-doc function description from just prior to __start_dirop()
to just before start_dirop() to avoid these kernel-doc warnings:

Warning: fs/namei.c:2853 function parameter 'state' not described
 in '__start_dirop'
WARNING: fs/namei.c:2853 expecting prototype for start_dirop().
 Prototype was for __start_dirop() instead

Fixes: ff7c4ea11a05 ("VFS: add start_creating_killable() and start_removing_killable()")
