Subject: RDMA/hns: Delete redundant condition judgment related to eq
Patch-mainline: v5.13-rc1
Git-commit: 714a597baab099e728307768e3b5c3b82d7b2ce3
References: bsc#1104427 FATE#326416

The register value related to the eq interrupt depends only on
enable_flag, so the redundant condition judgment is deleted.

Fixes: a5073d6054f7 ("RDMA/hns: Add eq support of hip08")
