Since RXE always posts RDMA_WRITE successfully, it's observed that
no more completion occurs after a few incorrect posts. Actually, it
will block the polling. we can easily reproduce it by the below pattern.
a. post correct RDMA_WRITE
b. poll completion event
while true {
c. post incorrect RDMA_WRITE(wrong rkey for example)
d. poll completion event <<<< block after 2 incorrect RDMA_WRITE posts
}
