firehose_read() uses -errno to denote errors, -1 to represent NAK, 1 to represent ACK and 0 to represent that we got a LOG and should read again. This choice is unintuitive and choosing to overload errno and NAK on the negative value space isn't awesome. Additionally, firehose_run() does in some cases return -errno and others -1. Clean this up by defining ACK and NAK in the non-negative value space and use the negative value space for errno. Use -EAGAIN to signal that firehose_read() should make another read attempt.
