net/sched: sch_qfq: reintroduce lmax bound check for MTU

Browse source

25369891fc deletes a check for the case where no 'lmax' is
specified which 3037933448 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.
