3.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Or Gerlitz <ogerlitz@mellanox.com>
commit 450d1e40d597dd71843457c73d372c4b4f2a83eb upstream.
Commit 819a087316a6 ("IB/iser: Avoid error prints on EAGAIN registration failures") not only eliminated the error print on that case, but rather also modified the code such that it doesn't return any error to upper layers. As a result a wrong mapping was used. Fix this to correctly return the error in that case.
