Subject: [PATCH] [Bugfix] Set `ACL_OP_INIT_MODE` env var default to `0`
 (#1123)

### What this PR does / why we need it?

Set `ACL_OP_INIT_MODE` env var default to `0`, since vllm-ascend may
have problems in some scenarios when setting it to `1`.

Plus, the guide https://github.com/vllm-project/vllm-ascend/issues/734
has also been updated.
