[PATCH -next] perf/arm_dmc620_pmu: Fix error return code in dmc620_pmu_device_probe()

['Wei Yongjun]

From: Wei Yongjun <weiyongj...@huawei.com>

Fix to return negative error code -ENOMEM from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 53c218da220c ("driver/perf: Add PMU driver for the ARM DMC-620 memory 
controller")
