net: enetc: use PCI device name for debugfs directory
enetc_create_debugfs() is called right after register_netdev(), at which
point ndev->name still holds the format "eth%d" (e.g., eth0) rather than
the final assigned name (e.g., via udev rules).
Use pci_name() instead of netdev_name() to name the debugfs directory.
The PCI device name is unique, stable, and available from the start,
making it a more reliable identifier for the debugfs entry. Therefore,
the observable debugfs path from something like
/sys/kernel/debug/eth0/mac_filter to a PCI BDF-style path such as
/sys/kernel/debug/0002:00:00.0/mac_filter.
