net: Only store high 16 bits of kernel generated filter priorities
The kernel should only be using the high 16 bits of a kernel generated priority. Filter priorities in all other cases only use the upper 16 bits of the u32 'prio' field of 'struct tcf_proto', but when the kernel generates the priority of a filter is saves all 32 bits which can result in incorrect lookup failures when a filter needs to be deleted or modified.
