Fix pcm_read_seek () when the position it calculates is greater than 2 GB.

pcm_read_seek() puts the return value of url_fseek() in an int and then
compares < 0 to see if an error occurred; if the position is greater
than 2 GB, the 32-bit signed int result will be < 0.

Change the type of ret to int64_t to avoid the wraparound.
