Revert "task_struct: make journal_info conditional"
This reverts commit e4c570c4cb7a95dbfafa3d016d2739bf3fdfe319, as
requested by Alexey:
"I think I gave a good enough arguments to not merge it.
To iterate:
* patch makes impossible to start using ext3 on EXT3_FS=n kernels
without reboot.
* this is done only for one pointer on task_struct"
None of config options which define task_struct are tristate directly
or effectively."
