rtlwifi: Fix fallback firmware loading
commit 1d9b168d8ea9a0f51947d0e2f84856e77d2fe7ff upstream. Commit f70e4df2b384 ("rtlwifi: Add code to read new versions of firmware") added code to load an old firmware file if the new one is not available. Unfortunately that code is never reached because request_firmware_nowait() does not wait for the firmware to show up and returns 0 even if the file is not there. Use the existing fallback mechanism introduced by commit 62009b7f1279 ("rtlwifi: rtl8192cu: Add new firmware") instead.
