[PATCH 2/4] ARM perf: Fix the pmu node name in warning message

With commit 9fd85eb502a7 ("ARM: pmu: add support for interrupt-affinity
property"), we print a warning when we find a PMU SPI with a missing
missing interrupt-affinity property in a pmu node. Unfortunately, we
pass the wrong (NULL) device node to of_node_full_name, resulting in
unhelpful messages such as:

hw perfevents: Failed to parse <no-node>/interrupt-affinity[0]

This patch fixes the name to that of the pmu node.

Fixes: 9fd85eb502a7 (ARM: pmu: add support for interrupt-affinity property)
