[MPlayer-dev-eng] [PATCH] Fix mp_describe_titleset and related in stream_dvd.c

[kiriuja]

This patch corrects a few problems introduced by the commit that added
STREAM_CTRL_GET_TIME_LENGTH control in stream_dvd.c:

1. mp_describe_titleset opened by didn't close a vts if it didn't have
a vtsi_mat or vts_pgcit.

2. if(tt_srpt->title[title_no].title_set_nr == vts_no) check moved to
mp_get_titleset_length and so mp_describe_titleset produced heaps of
wrong output.

3. STREAM_CTRL_GET_TIME_LENGTH control wrongly assumed that every title
has its own vts. Need to use title_set_nr from tt_srpt->title instead.

4. mp_describe_titleset didn't return a value on success.

Someone please apply.
