qcacld-3.0: Properly validate QCA_WLAN_VENDOR_ATTR_NDP_IFACE_STR

Forráskód böngészése 
Currently the QCA_WLAN_VENDOR_ATTR_NDP_IFACE_STR nla_policy specifies
a type of NLA_STRING, but the underlying implementation expects a
NUL-terminated string. Update the policy to correctly use a type of
NLA_NUL_STRING with the len updated to remove the allocation needed
for the terminating NUL.
