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

Browse Source 
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: 7e78dd816e ("RDMA/hns: Clear extended doorbell info before using")
