dm zoned: remove duplicate nr_rnd_zones increase in dmz_init_zone() 

[ Upstream commit b8fdd09037 ]

zmd->nr_rnd_zones was increased twice by mistake. The other place it
is increased in dmz_init_zone() is the only one needed:

1131                 zmd->nr_useable_zones++;
1132                 if (dmz_is_rnd(zone)) {
1133                         zmd->nr_rnd_zones++;
