Rusty Russell 55c2d7884e lguest: don't look in console features to find emerg_wr. ... The 1.0 spec clearly states that you must set the ACKNOWLEDGE and DRIVER status bits before accessing the feature bits. This is a problem for the early console code, which doesn't really want to acknowledge the device (the spec specifically excepts writing to the console's emerg_wr from the usual ordering constrains). Instead, we check that the *size* of the device configuration is sufficient to hold emerg_wr: at worst (if the device doesn't support the VIRTIO_CONSOLE_F_EMERG_WRITE feature), it will ignore the writes.
