Subject[PATCH 5.10 341/575] nvme-rdma: fix error code in nvme_rdma_setup_ctrl
Date
From: Max Gurtovoy <mgurtovoy@nvidia.com>

[ Upstream commit 09748122009aed7bfaa7acc33c10c083a4758322 ]

In case that icdoff is not zero or mandatory keyed sgls are not
supported by the NVMe/RDMA target, we'll go to error flow but we'll
return 0 to the caller. Fix it by returning an appropriate error code.

Fixes: c66e2998c8ca ("nvme-rdma: centralize controller setup sequence")
