decompress_bunzip2: off by one in get_next_block()
"origPtr" is used as an offset into the bd->dbuf[] array. That array is
allocated in start_bunzip() and has "bd->dbufSize" number of elements so
the test here should be >= instead of >.
Later we check "origPtr" again before using it as an offset so I don't
know if this bug can be triggered in real life.
Fixes: bc22c17e12c1 ('bzip2/lzma: library support for gzip, bzip2 and lzma decompression')
