lib: fix wrong returned value for filter

When setting rule for access-list ( and prefix-list ) without sequence, it
will automatically get a sequence by `acl_get_seq()`, and return
`CMD_SUCCESS` for command even this sequence value is wrong.

In this scene, `CMD_WARNING_CONFIG_FAILED` should be returned with a
warning.

So, add the check in `acl_get_seq()` and move `nb_cli_enqueue_change()`
after the check of wrong sequence.

Both `plist_remove_if_empty()` and `acl_remove_if_empty()` should ignore
this check, there is no change on them.

Before:
```
anlan(config)# access-list aa seq 4294967295 deny 6.6.6.6/32
anlan(config)# access-list aa deny 6.6.6.7/32  <- Return CMD_SUCCESS
YANG error(s):
 Value "4294967300" is out of uint32's min/max bounds.
 Value "4294967300" is out of uint32's min/max bounds.
 Value "4294967300" is out of uint32's min/max bounds.

```

After:
```
anlan(config)# access-list aa seq 4294967295 deny 6.6.6.6/32
anlan(config)# access-list aa deny 6.6.6.7/32  <- Return CMD_WARNING_CONFIG_FAILED
% Malformed sequence value
```

Additionally, fixed the overflow issue on `acl_get_seq()` on **32bit** platforms.
Just change the returned type of `acl_get_seq()` from `long` to `int64_t`.

Before:
```
anlan(config)# access-list bb seq 4294967295 deny 6.6.6.6/32
anlan(config)# access-list bb deny 6.6.6.7/32
anlan(config)# do show run
...
access-list bb seq 4294967295 deny 6.6.6.6/32
access-list bb seq 4 deny 6.6.6.7/32 <- Overflow
```

After:
```
anlan(config)# access-list bb seq 4294967295 deny 6.6.6.6/32
anlan(config)# access-list bb deny 6.6.6.7/32
% Malformed sequence value
```
