It's good to fix leak on error path, but this condition is *impossible*: if
BigTable was NULL, memset() above would die on SIGSEGV (and there are same
problem with K1table allocation above) [and both really cries for
"s/malloc/calloc/ and get rid of memset"]
(Of course, this is a bug in libdvdcss, not something that should be fixed by
this patch)
