fix the remaining ogv segfaults from issue 1240.
First commit:
Make decode_init fail if the huffman tables are invalid and thus init_vlc fails.
Otherwise this will crash during decoding because the vlc tables are NULL.
Partially fixes ogv/smclock.ogv.1.101.ogv from issue 1240.

Second commit:
Add extra validation checks to ff_vorbis_len2vlc.
They should not be necessary, but it seems like a reasonable precaution.
