RandomForestClassifier class_weight/max_samples interaction can lead to ungraceful and nondescriptive failure

### Describe the bug

The acceptable values for `max_samples` are `(0, 1]`. One possible option for `class_weight` is `balanced_subsample`. However, for values of `max_samples` near zero and `class_weight='balanced_subsample'`, the model fails with an unhelpful error related to having an empty array as an indexer.

This is only likely to come up in a grid search, as it seems unlikely that someone would deliberately force a subsample of zero items. However, it might be useful to have a minimum of one sample, or it might be useful to fail gracefully with a more descriptive error.


### Steps/Code to Reproduce

```python
from sklearn.datasets import load_wine
from sklearn.ensemble import RandomForestClassifier

X, y = load_wine(return_X_y=True)

clf = RandomForestClassifier(max_samples=1e-4, class_weight='balanced_subsample')
clf.fit(X,y)
```
### Expected Results

EITHER:
No error is thrown

OR
```
ValueError: insufficient samples for max_samples value
```

### Actual Results

```
