Remove check for NFAPI_MODE_AERIAL, it's pointless

In Aerial bindings (FAPI-Aerial), the NFAPI mode must be
NFAPI_MODE_AERIAL (otherwise, we would not be executing this code).
Hence, the switches don't make sense. Remove them.

The check can more easily be checked with

    git show <commit> --ignore-all-space
