Subject: [PATCH 4/4] nfs: sysfs: use default get_ownership() callback

Since commit 5f81880d5204 ("sysfs, kobject: allow creating kobject
belonging to arbitrary users") it seems that there could be cases for
kobjects belonging to arbitrary users. This callback is set by default
when using kset_create_and_add() to allow creating kobjects with
different ownerships according to its parent.

This patch will assign the default callback now for nfs kobjects for
cases when the parent has different ownership than the default one.
