flash: don't call vTaskDelay() before OS init

Browse Source 
PIOS_Flash_Jedec_EraseChip is called during early
init when the table_magic has changed.  This call
happens on CC/CC3D prior to the OS being initialized
so it is not OK to call vTaskDelay() yet.

This was leading to boards locking up (no flashing blue
LED) immediately after jumping to the application when
the table_magic had changed or was being init'd for the
very first time.
