Subject: [PATCH] arm64: perf: fix unassigned cpu_pmu->plat_device when probing
 PMU PPIs

Commit d795ef9aa831 ("arm64: perf: don't warn about missing
interrupt-affinity property for PPIs") added a check for PPIs so that
we avoid parsing the interrupt-affinity property for these naturally
affine interrupts.

Unfortunately, this check can trigger an early (successful) return and
we will not assign the value of cpu_pmu->plat_device. This patch fixes
the issue.
