refine_tet_add improper calls to get epsilonl

[millerta]

integer dsmin is used to get value of REAL epsilonl

discovered while checking use of cmo_get_attinfo and have not observed any issues.
Either this part of code is not being used or value is not used in a meaningful way.

When I check test return value of using integer dsmin, it is a garbage large number.

506 C           call get_epsilon('epsilonl', dsmin)
507             call cmo_get_attinfo('epsilonl',cmo_name,iout,dsmin,cout,
508      *           ipout,lout,itype,icscode)
