[PATCH] jbd doc: fix some kernel-doc warnings

Add structure fields kernel-doc for 2 fields in struct journal_s.

Warning(/var/linsrc/linux-2614-rc4//include/linux/jbd.h:808): No description found for parameter 'j_wbuf'
Warning(/var/linsrc/linux-2614-rc4//include/linux/jbd.h:808): No description found for parameter 'j_wbufsize'

Convert fs/jbd/recovery.c non-static functions to kernel-doc format.

fs/jbd/recovery.c doesn't export any symbols, so it should use
!I instead of !E to eliminate this warning message:

Warning(/var/linsrc/linux-2614-rc4//fs/jbd/recovery.c): no structured comments found
