[PATCH] ufs: fix oops with `ufs1' type
"rm" command, on file system with "ufs1" type cause system hang up. This is, in fact, not so bad as it seems to be, because of after that in "kernel control path" there are 3-4 places which may cause "oops". So the first patch fix oopses, and the second patch fix "kernel hang up". "oops" appears because of reading of group's summary info partly wrong, and access to not first group's summary info cause "oops".
