net: sched: Remove TCA_OPTIONS from policy

commit e72bde6b66299602087c8c2350d36a525e75d06e upstream.

Marco reported an error with hfsc:
root@Calimero:~# tc qdisc add dev eth0 root handle 1:0 hfsc default 1
Error: Attribute failed policy validation.

Apparently a few implementations pass TCA_OPTIONS as a binary instead
of nested attribute, so drop TCA_OPTIONS from the policy.

Fixes: 8b4c3cdd ("net: sched: Add policy validation for tc attributes")
