qemu_get_cm_event_timeout() neglects to set an error when it fails
because rdma_get_cm_event() fails. Harmless, as its caller
qemu_rdma_connect() substitutes a generic error then. Fix it anyway.
qemu_rdma_connect() also sets the generic error when its own call of
rdma_get_cm_event() fails. Make the error handling more obvious: set
a specific error right after rdma_get_cm_event() fails. Delete the
generic error.
