<div class='commit-subject'>svcrdma: avoid duplicate dma unmapping during error recovery</div><div class='commit-msg'>In rdma_read_chunk_frmr() when ib_post_send() fails, the error code path
invokes ib_dma_unmap_sg() to unmap the sg list. It then invokes
svc_rdma_put_frmr() which in turn tries to unmap the same sg list through
ib_dma_unmap_sg() again. This second unmap is invalid and could lead to
problems when the iova being unmapped is subsequently reused. Remove
the call to unmap in rdma_read_chunk_frmr() and let svc_rdma_put_frmr()
handle it.
Fixes: 412a15c0fe53 ("svcrdma: Port to new memory registration API")
