S3AInputStream read(bytes[]) to not retry on read failure: pass action up

The S3AInputStream reacts to read(byte[]) failure by reopening the stream, just as for the single byte read(). We shouldn't need to do that. Instead just close the stream, return 0 and let the caller decided what to do.

why so?

1. its in the contract of InputStream.read(bytes[]),
2. readFully() can handle the 0 in its loop
3. other apps can decided what to do.
