Commit 16dfa49406bc ("ice: Introduce new parameters in ice_sched_node") added a sched_node_ids xarray to the port info structure, but never called xa_destroy on it. Since xarrays can allocate internal memory, this can result in a memory leak even if every element in the xarray has been removed. Add a call to xa_destroy the structure during ice_deinit_hw(), and one to the unrolling cleanup path during errors in ice_init_hw(). While here, remove the overly verbose comment explaining the nature of the sched_node_ids xarray. This was caught by Sashiko during development of unrelated code.
