Fix generation of the subtitling descriptor

libdvbpsi | branch: master | Daniel Kamil Kozar <[email protected]> | Sun Jul 19 01:50:14 2015 +0200| [8278c52a487d45f3e865a56f25717d4184e11f2b] | committer: Jean-Paul Saman

Fix generation of the subtitling descriptor

The generation function for the subtitling descriptor erroneously uses the
modulo operation instead of a bitwise AND.
