Subject: Target/iser: Gracefully reject T10-PI enabled connect request if not
supported
From: Sagi Grimberg <[email protected]>
commit 5f80ff8eccba50832dcc640ac89add4c7fced963 upstream.
In case user chose to set T10-PI enable on the target while
the IB device does not support it, gracefully reject the request.
