From: Wenpeng Liang <liangwenpeng@huawei.com>

[ Upstream commit 4ddeacf68a3dd05f346b63f4507e1032a15cc3cc ]

Whether to enable the these features should better depend on the enable
flags, not the value of related fields.

Fixes: 5c1f167af112 ("RDMA/hns: Init SRQ table for hip08")
Fixes: 3cb2c996c9dc ("RDMA/hns: Add support for SCCC in size of 64 Bytes")
