tc: filter: validate filter priority in userspace.

Because we use the high 16 bits of tcm_info to pass prio value to
kernel, thus it's range would be [0, 0xffff], without validation
in tc when user pass a lager(>65535) priority, the actual priority
set in kernel would confuse the user.

So, add a validation to ensure prio in the range.
