patch fixing the bug (taken from jfsutils 1.1.14)

User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2b6pre)
Gecko/20091209

When checking a JFS filesystem after on an incorrectly finished system I
encountered a (reproducible) segfault in jfs_fsck, file libfs/log_work.c, line
2951. The segfault is caused by function updatePage() not checking sanity of
some values read from the log. This bug is fixed in jfsutils 1.1.13.

Attached is a fix taken from jfsutils 1.1.14 which can be used for OpenSuSE
11.1 and 11.2 (I didn't check older versions). For 11.3, update to jfsutils
1.1.14 would be preferrable (as suggested by #555093).

Reproducible: Sometimes
