perf arm-spe: Only warn once for each unsupported address packet

Browse source

Unknown address packet indexes are not an error as the Arm architecture
can (and has with SPEv1.2) define new ones and implementation defined
ones are also allowed. The error message for every occurrence of the
packet is needlessly noisy as well. Change the message to print just
once for each unknown index.
