RDMA/hns: Fix HW configurations not cleared in error flow

[ Upstream commit 998b41cb20b02c4e28ac558e4e7f8609d659ec05 ]

hns_roce_clear_extdb_list_info() will eventually do some HW
configurations through FW, and they need to be cleared by
calling hns_roce_function_clear() when the initialization
fails.
