Delete enable interrupts in xPortStartScheduler() #2

@yehuda-bernstein

Description

@yehuda-bernstein

The line portENABLE_INTERRUPTS(); in the function xPortStartScheduler(void) should be removed.
This might cause the context to run in main() stack and crash the system.
See remark at function void vTaskStartScheduler( void ) lines 2064-2068:

/ Interrupts are turned off here, to ensure a tick does not occur
* before or during the call to xPortStartScheduler(). The stacks of
* the created tasks contain a status word with interrupts switched on
* so interrupts will automatically get re-enabled when the first task
* starts to run. /

BaseType_t xPortStartScheduler(void)
{
vPortSetupTimerInterrupt();

ulCriticalNesting = 0;

#if(configUSE_PREEMPTION == 1)
bPreemptive = 1;
#else
bPreemptive = 0;
#endif

portENABLE_INTERRUPTS();
portRESTORE_FIRST_CONTEXT();

// Should not get here!
return pdFAIL;
}
