t/one-core-peak: Don't report errors if missing NVME features
Some NVMEs doesn't support some features, an error message is reported
like in the following example :
NVMe status: INVALID_FIELD: A reserved coded value or an unsupported value in a defined field(0x4002)
nvme2n1: Temp:26 C, Autonomous Power State Transition:, PowerState:0, Completion Queues:135, Submission Queues:135
This commit will only report features if available :
nvme2n1: Completion Queues:135, Submission Queues:135, PowerState:0, Temp:27 C
