Recent commit 3b8786ff7a1b31645ae2c26a2ec32dbd42ac1094
("ARM: 8352/1: perf: Fix the pmu node name in warning message")
introduced a memory leak of irqs on the "Don't bother with PPIs"
return path. This was picked up by static analysis by cppcheck:

[arch/arm/kernel/perf_event_cpu.c:315]: (error) Memory leak: irqs

simpele fix is to free irqs when returning.
