ocfs2-tools: avoid evaluating a garbage value.

* fsck.ocfs2/journal.c: Variable 'jis' declared without an initial value then
  branch condition evaluates to a garbage value in 'out' section when the 
  first 'if (ret)' is ture.
* fsck.ocfs2/pass1b.c: Variable 'ret' declared without an initial value then 
  branch condition evaluates to a garbage value in 'out' section when 
  'if (pc->ret)' is ture.
* libocfs2/slot_map.c: when the first 'if (ret)' is ture, the codes will jump
  into 'out' section, however, the statement 'ocfs2_read_cached_inode(fs, blkno, &sf.ci)' 
  hasn't been executed, so 'sf.ci' is a garbage value.
* mounted.ocfs2/mounted.c: Variable 'proc' declared without an initial value,
  when 'if (device)' and the first 'if (ret)' are ture, the codes will jump
  into 'bail' section, however, the statement 'proc = fopen ("/proc/partitions", "r")'
  hasn't been executed, so 'proc' is a arbage value.
