net/sched: fix error recovery in qdisc_create()
If TCA_STAB attribute is malformed, qdisc_get_stab() returns
an error, and we end up calling ops->destroy() while ops->init()
has not been called yet.
While we are at it, call qdisc_put_stab() after ops->destroy().
Fixes: 1f62879e3632 ("net/sched: make stab available before ops->init() call")
