INTERPOLATION: kappa parameter should be >= 1.

Browse Source 
The kappa parameter is calculated from CFL value. It is a decreasing
value with increasing CFL. However, to maintain the precision of MP
limiter, it should be kept above 1. Therefore, instead of taking the min
values between the user defined kappa and the one calculated from the
CFL value, take its maximum.
