[patch 2/3] ext3: Fixup rb_root initializations to use RB_ROOT

[venkatesh.pallipadi@intel.com]

ext3 uses rb_node = NULL; to zero rb_root.
The problem with this is that 17d9ddc72fb8bba0d4f678 in the
linux-next tree adds a new field to that struct which needs to be NULLas well.
This patch uses RB_ROOT as the intializer so all of the relevant fields will
be NULL'd.
