freertos: Fix xTaskIncrementTick for unwind the Tick for CPU1

Browse Source 
xTaskIncrementTick have to unwind uxPendedTicks on CPU1 and CPU0.

Use case: If an erase operation was run on the CPU1 then it leads
to starving other tasks which waiting time. Waited tasks just skipped.

Closes: https://github.com/espressif/esp-idf/issues/1952

Closes: IDF-183
