Filippo Valsorda 1c2c788b11 chacha20: don't panic encrypting the final blocks

Certain operations with counter values close to overflowing were causing
an unnecessary panic, which was reachable due to the SetCounter API and
actually observed in QUIC.

Tests by lukechampine <luke.champine@gmail.com> from CL 220591.

Fixes golang/go#37157
