dpaa2-mac: Fix potential null pointer dereference

Browse source

There is a null-check for _pcs_, but it is being dereferenced
prior to this null-check. So, if _pcs_ can actually be null,
then there is a potential null pointer dereference that should
be fixed by null-checking _pcs_ before being dereferenced.
