Daniel P. Berrangé 5f87072e95 migration: remove unreachable code after reading data 
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
