xprtrdma: Use ro_unmap_sync in xprt_rdma_send_request
The "safe" version of ro_unmap is used here to avoid waiting unnecessarily. However: - It is safe to wait. After all, we have to wait anyway when using FMR to register memory. - This case is rare: it occurs only after a reconnect. By switching this call site to ro_unmap_sync, the final use of ro_unmap_safe is removed. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
