Subject: [PATCH -next] RDMA/hns: remove set but not used variable 'irq_num'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/infiniband/hw/hns/hns_roce_hw_v2.c: In function hns_roce_v2_cleanup_eq_table:
drivers/infiniband/hw/hns/hns_roce_hw_v2.c:5920:6:
 warning: variable irq_num set but not used [-Wunused-but-set-variable]

It is not used since
commit 33db6f94847c ("RDMA/hns: Refactor eq table init for hip08")
