multipath: Fix off-by-one in hash_threshold multipath calculation.

0xffffffff / (0xffffffff / n) can have a value as large as n (consider the
n == 1 case), but we need a value no bigger than n-1.  So add 1 before
dividing to fix the problem.

This caused a test failure on Debian "lenny" amd64 when apparently
unrelated code changed.
