pgsql: Fix incorrect assertion bound in WaitForLSN()

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().
