Subject: RDMA/hns: Fix assignment to ba_pg_sz of eqe
Patch-mainline: v5.8-rc1
Git-commit: 053c0acf52edf97cae7d53c9f249f7c2eb565ed9
References: jsc#SLE-14777

When allocating eq buffer, the size of base address page should be defined
by eqe_ba_pg_sz instead of srqwqe_ba_pg_sz.

Fixes: 477a0a387072 ("RDMA/hns: Optimize 0 hop addressing for EQE buffer")
