sort: fix bug on 64-bit hosts with at least 32768 processors

* src/sort.c (MAX_MERGE): Avoid integer overflow when on a machine
with (say) 32-bit int and 64-bit size_t and when level == 15.
Without this fix, on such a machine with 32768 or more processors,
the level computation could overflow on large input, and this
would result in division by zero.
