[PKT_SCHED]: Fix missing qdisc_destroy() in qdisc_create_dflt()
qdisc_create_dflt() is missing to destroy the newly allocated default qdisc if the initialization fails resulting in leaks of all kinds. The only caller in mainline which may trigger this bug is sch_tbf.c in tbf_create_dflt_qdisc(). Note: qdisc_create_dflt() doesn't fulfill the official locking requirements of qdisc_destroy() but since the qdisc could never be seen by the outside world this doesn't matter and it can stay as-is until the locking of pkt_sched is cleaned up.
