rtlwifi: rtl8723ae: rtl8723be: rtl8723com: Fix firmware header endian issues

The drivers are converted to use the common firmware header struct.
Because the old header definition failed to indicate that the multi-byte
entries should be little endian, several problems were thus exposed.
These are fixed.
