From: Dinghao Liu <dinghao.liu@xxxxxxxxxx> [ Upstream commit 3b01d7ea4dae907d34fa0eeb3f17bacd714c6d0c ] When sdeb_zbc_model does not match BLK_ZONED_NONE, BLK_ZONED_HA or BLK_ZONED_HM, we should free sdebug_q_arr to prevent memleak. Also there is no need to execute sdebug_erase_store() on failure of sdeb_zbc_model_str().
