Fix incorrect assertion bound in WaitForLSN()
The assertion checking MyProcNumber used MaxBackends as the upper
bound, but the procInfos array is allocated with size
MaxBackends + NUM_AUXILIARY_PROCS. This inconsistency would cause
a false assertion failure if an auxiliary process calls WaitForLSN().
