qcacmn: Fix NDP Config QoS policy

The qca_wlan_vendor_ndp_policy for the attribute
QCA_WLAN_VENDOR_ATTR_NDP_CONFIG_QOS currently specifies type
NLA_BINARY with a maximum length of NDP_QOS_INFO_LEN (255). However
this attribute is defined to be an unsigned 32 bit value, and
nla_get_u32() is used to read the value, so change the policy to use
type NLA_U32 so that nla_parse() can properly verify that the TLV
payload has (at least) 4 bytes of data.
