Richard Guo 7c82b4f711 Fix integer-overflow problem in scram_SaltedPassword()
Setting the iteration count for SCRAM secret generation to INT_MAX
will cause an infinite loop in scram_SaltedPassword() due to integer
overflow, as the loop uses the "i <= iterations" comparison.  To fix,
use "i < iterations" instead.

Back-patch to v16 where the user-settable GUC scram_iterations has
been added.
