With flag NULL, val is returned from getopt_long().
Since long option --do-active is short option -Z, val should be capital 'Z'
so the switch construct matches case 'Z' as for the short option.
Otherwise --do-active would end up the same as -z which is --q2d-latencies.
Fixes btt v2.09 in blktrace v1.0.2.
