net: sched: sch_multiq: fix possible OOB write in multiq_tune() 



q->bands will be assigned to qopt->bands to execute subsequent code logic
after kmalloc. So the old q->bands should not be used in kmalloc.
Otherwise, an out-of-bounds write will occur.

Fixes: c2999f7f ("net: sched: multiq: don't call qdisc_put() while holding tree lock")
