What does this PR do?

Fixes #12830

Also if there are insufficient batches when using limi_train_batches=float (for eg, total batches=9 and limit_train_batches=0.1), it is used to silently disable the training. Ideally, it should raise an error just like it does with eval dataloaders.

Also, it is weird that when the input dataloaders have no batches, it just raises a warning and doesn't do anything but for the above case, it raises an exception. IMO we should start raising an exception in this case too?
