mp3dec: Fix possibly exploitable crash

I was sadly unable to find a non fuzzed mp3 that uses the
feature that contained the bug (and i searched hard ...), thus
while this fixes the security issue. It may or may not fix
mixed blocks in 8khz mp3s, i cant say due to lack of samples to test.

Security issue exists since: b37d945dd4213cb8e92146571b0374cd45d52286
