In commit 38506ecefab9 ("rtlwifi: rtl_pci: Start modification for new drivers"), a callback to get the RX buffer address was added to the PCI driver. Unfortunately, driver rtl8192de was not modified appropriately and the code runs into a WARN_ONCE() call. The use of an incorrect array is also fixed.
