[PATCH] bluetooth: hci_h5: avoid unused variable warnings

[Arnd Bergmann]

When CONFIG_BT_HCIUART_RTL is disabled, the hci_h5 driver produces a build
warning because of an incorrect set of #ifdef guards:

drivers/bluetooth/hci_h5.c:920:22: error: 'rtl_vnd' defined but not used [-Werror=unused-variable]

Replacing the #ifdef with an IS_ENABLED() check shuts up the error
and simplifies the logic.
