ipaccess_drop_oml(): invalidate the feature vector
It's possible that a BTS gets disconnected, updated to a more recent
version or downgraded to an older version, and then connects to the
BSC again. That more recent or older BTS version may have a different
set of supported features, so osmo-bsc must not trust the previously
reported feature vector.
