[ Upstream commit b5df9b7a2f965b7903850d8f89846ffe0080b84b ]

According to the IB Specification, srq_limit shouldn't be configured
during SRQ creation. If a user set srq_limit at this time, the driver
should forced it to zero, or the result of creating SRQ will conflict with
the result of querying SRQ.

Fixes: c7bcb13442e1 ("RDMA/hns: Add SRQ support for hip08 kernel mode")
