perf: arm_dsu: Fix hotplug callback leak in dsu_pmu_init()
dsu_pmu_init() won't remove the callback added by cpuhp_setup_state_multi()
when platform_driver_register() failed. Remove the callback by
cpuhp_remove_multi_state() in fail path.
Similar to the handling of arm_ccn_init() in commit 26242b330093 ("bus:
arm-ccn: Prevent hotplug callback leak")
Fixes: 7520fa99246d ("perf: ARM DynamIQ Shared Unit PMU support")
