Merge branch 'susburrows/atm/bugfix-ice_itd-array-syntax' (PR #400)

Fix bug in array syntax in ice_itd.F90

Fixes an error encountered when compiling with intel DEBUG mode on
edison. In this bug, the code fails at runtime in ice_itd.F90 with a
message stating:

"Subscript #1 of the array ATRCR has value 1 which is greater than the
upper bound of 0"

This is fixed as described on DiscussCESM
(https://bb.cgd.ucar.edu/error-running-compset-fsdwsf-ert), by
removing the explicit array syntax in the call to compute_tracers().

Fixes #339
