ext4: fix #11321: create /proc/ext4/*/stats more carefully
(cherry picked from commit 899fc1a4cf404747de2666534d508804597ee22f)
ext4 creates per-suberblock directory in /proc/ext4/ . Name used as
basis is taken from bdevname, which, surprise, can contain slash.
However, proc while allowing to use proc_create("a/b", parent) form of
PDE creation, assumes that parent/a was already created.
bdevname in question is 'cciss/c0d0p9', directory is not created and all
this stuff goes directly into /proc (which is real bug).
Warning comes when _second_ partition is mounted.
