[PATCH 02/12] HPPFS: don't check sb->s_op in is_pid()

["Paolo 'Blaisorblade' Giarrusso" <blaisorblade@yahoo.it>]

From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>, Al Viro

To check whether a directory in /proc is a "pid" directory, we also check
(uselessly) whether the super_operations match the HPPFS ones. Drop that,
as suggested by Al Viro. Cleanup codingstyle in nearby code, btw.

Actually, we don't know why we used to do this. Just guessing.
