rdma: remove reqs from read/write queues in error

Browse Source 
Not doing so can cause us to hit asserts during the shutdown path. This
should fix an intermittent failure we are seeing on the test pool where
we hit the assert rdma_req->state != RDMA_REQUEST_STATE_FREE in
spdk_nvmf_rdma_request_process.

Note that this problem doesn't cause any data corruption when debug is
not enabled, it just causes us to probcess a subset of commands through
the state machine one extra time suring qpair shutdown.
