Subject: [PATCH 1/2] ext4: clean up ext4_dirty_inode()

This patch cleans up ext4_dirty_inode(); it's attempt to detect non-matching
transactions can never be executed.

	Signed-off-by: Curt Wohlgemuth <curtw@...gle.com>

If 'current_handle' is non-NULL, then ext4_start_journal() will return the
same handle with it's h_ref count incremented, and the h_transaction
pointers will be the same.
