RDMA/hns: Force srq_limit to 0 when creating SRQ

Browse Source 
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: c7bcb13442 ("RDMA/hns: Add SRQ support for hip08 kernel mode")
