Fix decode and generation of linkage descriptor with mobile handover

libdvbpsi | branch: master | Daniel Kamil Kozar <[email protected]> | Sat Jul 18 19:59:57 2015 +0200| [9e9cc85fbfc80ed74b80434073d617f82ad95933] | committer: Jean-Paul Saman

Fix decode and generation of linkage descriptor with mobile handover

Linkage descriptor's generation and decoding routines improperly calculated the
beginning of the private data region in cases where linkage_type = 8,
handover_info = 0, and origin_type = 1.
