jbd2: clean up how the journal device name is printed
Calculate the journal device name once and stash it away in the journal_s structure. This avoids needing to call bdevname() everywhere and reduces stack usage by not needing to allocate an on-stack buffer. In addition, we eliminate the '/' that can appear in device names (e.g. "cciss/c0d0p9" --- see kernel bugzilla #11321) that can cause problems when creating proc directory names, and include the inode number to support ocfs2 which creates multiple journals with different inode numbers.
