DecryptCbcs doesn't work with a 0:0 pattern. It will get stuck in a hot loop because the processing code assumes that we will process at least 1 block of data.
I think that a 0:0 pattern is unintuitive, but it's the convention for full encryption (which means all audio will use it). So let's not fail when we run into it.

This may be the cause of bug 1644879. Will check that once I fix, and dupe if needed.
