rt2x00: Only specify interface combinations if more then one interface is possible
Otherwise rt2500* triggers a warning in cfg80211, from net/wireless/core.c:
/* Combinations with just one interface aren't real */
if (WARN_ON(c->max_interfaces < 2))
This was introduced in commit 55d2e9da744ba11eae900b4bfc2da72eace3c1e1:
rt2x00: Replace open coded interface checking with interface combinations.
