[shoyokota]

In debugging the RRFS, issues of undefined values and thread safety was found in intrad.f90. The following issues should be fixed.

• tdir(1:nsigradjac) is undefined for variables except for (tsen,q,oz,cw,ql,qi,qh,qg,qr,qs,u,v,sst).
• val_quad and mm that should be private variables of OpenMP are public variables.
