[08/90] jbd2: Annotate transaction start also for jbd2_journal_restart()

[Greg KH]

2.6.31-stable review patch.  If anyone has any objections, please let us know.

------------------
(cherry picked from commit 9599b0e597d810be9b8f759ea6e9619c4f983c5e)

lockdep annotation for a transaction start has been at the end of
jbd2_journal_start(). But a transaction is also started from
jbd2_journal_restart(). Move the lockdep annotation to start_this_handle()
which covers both cases.
