Fix decoder handling of floor0 when the LSP order is 1.
Header setup allows the LSP order to be as low as one, but the code in vorbis_lsp_to_curve() assumed it was at least two. This wasn't terrible in libvorbis... it would multiply a nonsense (but defined) value into the output, and nothing more. In Tremor, it referenced several completely undefined (stack) values, which could cause out-of-bounds lookup table accesses and crashes. git-svn-id: https://svn.xiph.org/trunk/Tremor@17538 0101bb08-14d6-0310-b084-bc0e0c8e3800
