tasks.c: disable interrupts in critical section only if scheduler is started

Browse source 
Behaviour of `vTaskEnterCritical` and `vTaskExitCritical` was asymmetrical,
in the sense, if these APIs were invoked prior to scheduler start condition
then one would disable interrupts but other would not re-enable again.
This commit ensure that behaviour is symmetrical for pre-scheduler start
condition.
