Chengguang Xu 38a3499f6d block: loop: check error using IS_ERR instead of IS_ERR_OR_NULL in loop_add() 
blk_mq_init_queue() will not return NULL pointer to its caller,
so it's better to replace IS_ERR_OR_NULL using IS_ERR in loop_add().

If in the future things change to check NULL pointer inside loop_add(),
we should return -ENOMEM as return code instead of PTR_ERR(NULL).
