From: Daniel P. Berrangé <berra...@redhat.com>
The code calls qio_channel_read() in a loop when it reports
QIO_CHANNEL_ERR_BLOCK. This code is reported when errno==EAGAIN.
As such the later block of code will always hit the 'errno != EAGAIN'
condition, making the final 'else' unreachable.
Fixes: Coverity CID 1490203
