Piror to this patch, outstanding_rdma was increased after rdma request was sent. This could cause mca_btl_ofi_flush() to return before the rdma submitted by the caller completed under multi-thread environment.
To address, this patch moved the increment of outstanding_rdma to before RDMA requests were submitted, and decrease the counter when submission failed.
