Fixing remaining issues related to MPI buffer reuse

This commit fixes the remaining issues related to MPI buffer reuse in
the MPAS components. The landice model had a statistics module that
previously used the same buffer for sending and receiving.

Additionally, the sea ice driver previously had an incorrect variable
that was used to test time intervals.
