RDMA/hns: Fix warning storm caused by invalid input in IO path

Browse Source 
[ Upstream commit fa5c4ba8cd ]

WARN_ON() is called in the IO path. And it could lead to a warning
storm. Use WARN_ON_ONCE() instead of WARN_ON().

Fixes: 12542f1de1 ("RDMA/hns: Refactor process about opcode in post_send()")
