[Qemu-devel] [PULL v1 02/10] io: Use qio_channel_has_feature() where applicable

["Daniel P. Berrange" <berrange@redhat.com>]

From: Felipe Franciosi <felipe@nutanix.com>

Parts of the code have been testing QIOChannel features directly with a
logical AND. This patch makes it all consistent by using the
qio_channel_has_feature() function to test if a feature is present.
