When allocations fails that can be NULL now. If the name provided is NULL, then the initialization process of the PMU type and dev will be skipped in function perf_pmu_register(). Consequently, the PMU will not be able to register into the kernel. Moreover, in the case of unregister the PMU, the function device_del() will need to handle NULL pointers, which potentially can cause issues. So move this allocation above the cpuhp_state_add_instance() and directly return if it does fail.
