Subject: [PATCH] fs: namei: use __pure modifier as declared in headers

sparse complains about different modifiers here. The function definitions
should simply use their declarations' modifiers.

We also shrink the text width to our 80 characters maximum while we are
at it. This makes it sparse- and checkpatch-clean.
