Subject: [PATCH] UBIFS: fixup merged 'UBIFS: fix-up free space earlier'

When the patch 'UBIFS: intialize LPT earlier' was massaged before being applied
the context of the next patch 'UBIFS: fix-up free space earlier' was muddled
sufficiently for the order of allocate-lpt then free-space-fixup was reversed --
I think.

Put the free-space-fixup after allocate-lpt.

Signed-off-by: Ben Gardiner <bengardiner@...ometrics.ca>

With this fixup applied on-top-of the ubifs-2.6 master I am able to mount a
ubinized image containing a UBIFS volume which has the free-space-fixup flag
set. No assertions are displayed.
