zloop: fix the error code in the blk_mq_alloc_disk message

When blk_mq_alloc_disk() fails, "ret" still holds the zero returned by the
preceding blk_mq_alloc_tag_set() call, so the error message always reports
"err=0".  Save PTR_ERR(zlo->disk) in "ret" before printing it, like the
blk_mq_alloc_tag_set() and add_disk() failure paths do.
