[nrf fromtree] net: openthread: fix received frame flags

edmont · carlescufi · commit 0a1769c50c28 · 2022-02-24T11:31:45.000+01:00
Uninitialized memory would report wrong value for
`mAckedWithSecEnhAck` flag in the received frame, making the
OpenThread stack to update the frame counter for the neighbor
wrongly.
