perf/arm_dmc620: Fix hotplug callback leak in dmc620_pmu_init()
dmc620_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: 53c218da220c ("driver/perf: Add PMU driver for the ARM DMC-620 memory controller")
