The sub-directory of hns_roce debugfs is named after the device's
kernel name currently, but it will be inconvenient to use when
the device is renamed.
Modify the name to pci name as users can always easily find the
correspondence between an RDMA device and its pci name.
Fixes: eb7854d63db5 ("RDMA/hns: Support SW stats with debugfs")
