examples/nvme/identify: set features valid flag to false before getting new value

Browse Source 
features are global variable and can be used for different controllers, e.g: there
are 2 controllers, the first one can support Arbitration feature, and the second
controller can't support Arbitration feature, the value from features[fid].valid
may contain the first drive's old value.
