The problem is that Quirrell can't cast any spells on Harry. And, furthermore, Quirrell really doesn't want Dumbledore to find this out - Dumbledore already knows of a certain other person with an unexpected inability to cast spells on Harry Potter, and I think the hint would probably be enough for him to put the two together.
Oh, good point, I had forgot about that. In which case... Dumbledore may not be able to guess the telepathic link due to prior implausibility, but he should realize that there is something odd going on, if it crosses his mind to investigate how Quirrell knew where to go.
Of course, this may not occur for a while if at all, as Dumbledore has plenty of other things to worry about, and the obvious suspect from his POV is Lord Malfoy.
