RDMA/hns: Fix HW configurations not cleared in error flow
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.
Fixes: 7e78dd816e45 ("RDMA/hns: Clear extended doorbell info before using")
