Subject: i40iw: Validate correct IRD/ORD connection parameters

From: Tatyana Nikolova <[email protected]>

[ Upstream commit ce9ce74145aa6814a370a9ff4f5a1d719baaced1 ]

Casting to u16 before validating IRD/ORD connection parameters could cause recording wrong IRD/ORD values in the cm_node. Validate the IRD/ORD parameters as they are passed by the application before recording them.
