This breaks out/combines get_affine_portal and the cgr sanity check in
preparation for the next commit. No functional change intended.

[ Upstream commit 584c2a9184a33a40fceee838f856de3cffa19be3 ]
smp_call_function_single disables IRQs when executing the callback. To
prevent deadlocks, we must disable IRQs when taking cgr_lock elsewhere.
This is already done by qman_update_cgr and qman_delete_cgr; fix the
other lockers.
