[PATCH] Bluetooth: btmtk: fix handling of CONFIG_DEV_COREDUMP not being defined

[Tom Rix]

When CONFIG_DEV_COREDUMP is not defined, there is this error
drivers/bluetooth/btmtk.c: In function ‘btmtk_process_coredump’:
drivers/bluetooth/btmtk.c:386:44: error: ‘struct hci_dev’ has no member named ‘dump’
  386 |                 schedule_delayed_work(&hdev->dump.dump_timeout,
      |                                            ^~

The runtime IS_ENABLED(CONFIG_DEV_COREDUMP) is not enough to
prevent the compiletime error of accessing the dump element of hci_dev.
So switch to #ifdef.
