firmware: replace #ifdef over FW_OPT_FALLBACK with function checks
Its not easy to follow the logic behind making FW_OPT_FALLBACK map
to an existing flag only if a kernel configuration option was set.
Its much easier to retpresent what was intended with function helpers
which make it clear that if CONFIG_FW_LOADER_USER_HELPER_FALLBACK is
set we force running the fallback mechanism unless a caller specifically
never wants to run it, such as request_firmware_direct().
Prior and after this change we upkeep the tradition:
CONFIG_FW_LOADER_USER_HELPER_FALLBACK
request_firmware() force fallback
request_firmware_into_buf() force fallback
request_firmware_nowait() force fallback
request_firmware_direct() always ignore fallback
!CONFIG_FW_LOADER_USER_HELPER_FALLBACK
request_firmware() ignore fallback
request_firmware_into_buf() ignore fallback
request_firmware_nowait() depends on uevent flag
request_firmware_direct() always ignore fallback
