Pedro Tammela 73e72a5380 net/sched: sch_qfq: reintroduce lmax bound check for MTU
commit 158810b261d02fc7dd92ca9c392d8f8a211a2401 upstream.

25369891fcef deletes a check for the case where no 'lmax' is
specified which 3037933448f6 previously fixed as 'lmax'
could be set to the device's MTU without any bound checking
for QFQ_LMAX_MIN and QFQ_LMAX_MAX. Therefore, reintroduce the check.

Fixes: 25369891fcef ("net/sched: sch_qfq: refactor parsing of netlink parameters")
