net: qed: fix async event callbacks unregistering
qed_spq_unregister_async_cb() should be called before
qed_rdma_info_free() to avoid crash-spawning uses-after-free.
Instead of calling it from each subsystem exit code, do it in one place
on PF down.
Fixes: 291d57f67d
("qed: Fix rdma_info structure allocation")
