Instead of removing the frees we allocated from heap.

Browse Source 
In SA mode, there were DCI_INDs and RX_INDS that
were allocated on the stack and were assigned to
pointers used in the MAC instance. In NSA mode we
allocated these members on the heap so we free'd
them once we were done. In SA mode, they were not
allocated on the heap so this free call caused an
a free() error. We have now allocated these pointers
on the heap to avoid this error and ensure the
pointers are correct.
