[web-nfc] android.nfc.NfcAdapter.enableReaderMode() has no failure cases (#242)

leonhsl has just created a new issue for https://github.com/w3c/web-nfc:

== android.nfc.NfcAdapter.enableReaderMode() has no failure cases ==
https://w3c.github.io/web-nfc/#dom-nfcreader-start step 3.2 says 
> make a request to all NFC adapters to listen to NDEF messages

and step 3.3 says 
> If the request fails, then
Let e be the result of creating a "NotSupportedError" DOMException.

android.nfc.NfcAdapter.enableReaderMode() [1] does what step 3.2 says, but this function always succeeds in registering a ReaderCallback for receiving notifications from the platform, it has no failure cases, so what does step 3.3 mean for 'If the request fails'?
