ibmvscsis: Fix srp_transfer_data fail return code
commit 7c9d8d0c41b3e24473ac7648a7fc2d644ccf08ff upstream.
If srp_transfer_data fails within ibmvscsis_write_pending, then
the most likely scenario is that the client timed out the op and
removed the TCE mapping. Thus it will loop forever retrying the
op that is pretty much guaranteed to fail forever. A better return
code would be EIO instead of EAGAIN.
