wifi: wilc1000: validate length of IEEE80211_P2P_ATTR_OPER_CHANNEL attribute

Browse source

Validate that the IEEE80211_P2P_ATTR_OPER_CHANNEL attribute contains
enough space for a 'struct struct wilc_attr_oper_ch'. If the attribute is
too small then it triggers an out-of-bounds write later in the function.
