Srinivas Dasari 0a27844ce8 cfg80211: Check if NAN service ID is of expected size 
nla policy checks for only maximum length of the attribute data when the
attribute type is NLA_BINARY. If userspace sends less data than
specified, cfg80211 may access illegal memory. When type is NLA_UNSPEC,
nla policy check ensures that userspace sends minimum specified length
number of bytes.

Remove type assignment to NLA_BINARY from nla_policy of
NL80211_NAN_FUNC_SERVICE_ID to make these NLA_UNSPEC and to make sure
minimum NL80211_NAN_FUNC_SERVICE_ID_LEN bytes are received from
userspace with NL80211_NAN_FUNC_SERVICE_ID.
