Previously, an incorrect index(1) for create-device is causing the 1st extra parameter to be ignored, which is wrong. For example: $ daxctl create-device region0 [ { "chardev":"dax0.1", "size":268435456, "target_node":1, "align":2097152, "mode":"devdax" } ] created 1 device where above user would want to specify '-r region0'. Check extra parameters starting from index 0 to ensure no extra parameters are specified for create-device.
