RDMA/srp: Propagate ib_post_send() failures to the SCSI mid-layer 



[ Upstream commit 2ee00f6a98c36f7e4ba07cc33f24cc5a69060cc9 ]

This patch avoids that the SCSI mid-layer keeps retrying forever if
ib_post_send() fails. This was discovered while testing immediate
data support and passing a too large num_sge value to ib_post_send().
