[Clp] Correction to CoinMP.cpp

[Rod Frowd]

Hi:

I found that the CoinMP.dll did not work when built from source, though 
the downloaded binary dll did.

Upon looking  at the source code I found the problem below, some of the 
real tolerance were being set to zero as the CoinGetIntOption was being 
called instead of the CoinGetRealOption? The built from source dll works 
after this change.

Do you want me to check this in?
