Subject: crypto: caam/qi - fix FD congestion weight
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When caam_qi_enqueue() is called, compound FD has already been swapped
to CAAM endianness, thus accesing it ("length" field in this case) by
CPU has to be done by first unswapping.

Fixes: ca982fae08a2 ("crypto: caam/qi - use QBMan (NXP) SDK driver")
