freertos: fix errors reported by PVS-Studio

Browse Source 
Removed leftover code-paths that were never taken. Upstream freertos uses
vTaskSuspendAll() and xTaskResumeAll(), and therefor check if the task already
yielded.

In the IDF port of freertos we use critcal sections instead, so xAlreadyYielded
will never be set.

Partially addresses https://github.com/espressif/esp-idf/issues/6440
