[Feature] Fix in InifiniteSampler.__iter__

[MzeroMiko]

What is the feature?

In mmegine.dataset.sampler.InfiniteSampler, would it better to change the function InifiniteSampler.iter to the following:

    def __iter__(self) -> Iterator[int]:
        """Iterate the indices."""
        # yield from self.indices
        try:
            for i in self.indices:
                yield i
        except StopIteration as e:
            self.indices = self._indices_of_rank()
            return self.__iter__()

the original code is

def __iter__(self) -> Iterator[int]:
        """Iterate the indices."""
        yield from self.indices

which may raise error when iter the dataloader more than once.

Any other context?
