[qca-nss-qdisc] Handle NULL opt

New version of TC provides a NULL netlink message when users dont configure
any of the supported tunable parameters. Therefore a create request with NULL
message is still valid and has to be processed.

This affects qdiscs that only have non-mandatory input parameters. In our
list of supported qdiscs nssbf, nsshtb and nssprio falls in this category.
