Fix intermediate overflow in op_pcm_total().

Although link enumeration ensures the return value is in range, the
 order of operations allows the intermediate value pcm_total+diff
 to overflow the range of a 64-bit int.
Add parentheses to ensure this does not happen.
Thanks to Felcia Lim for the report.

Fixes #2330
