Subject: [PATCH] Documentation/locking/lockdep: Drop last two chars of sample states

Since the removal of FS_RECLAIM annotations, lockdep states contain six
characters, not four.

Fixes: e5684bbfc3f03480 ("Documentation/locking/lockdep: Update info about states")
Fixes: d92a8cfcb37ecd13 ("locking/lockdep: Rework FS_RECLAIM annotation")
