Getting task info do not work for IDLE and Timer task when using MPU

[aggarg (Gaurav Aggarwal)]

Function xTaskGetHandle always return NULL when searching for idle task "IDLE" and timer task "Tmr Svc"

Use xTaskGetIdleTaskHandle and xTimerGetTimerDaemonTaskHandle.

@e_corini

Function vTaskGetInfo do not return correct data for idle and timer tasks. For example the field xHandle of the returned task status is different from the given handle

Which MPU wrapper are you using? Can you share the 2 values - the xHandle value that you provide and the returned one?
