drivers: perf: marvell_cn10k: Fix hotplug callback leak in tad_pmu_init()

tad_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 26242b33 ("bus:
arm-ccn: Prevent hotplug callback leak")
