The result of openfile was not checked, leading to failure deep in the
actual command with confusing error message, and exiting with exit code 0.
Here is a simple example - trying to read with the wrong format:
$ touch file
$ qemu-io -f qcow2 -c 'read -P 1 0 1024' file; echo $?
can't open device file: Image is not in qcow2 format
no file open, try 'help open'
0
With this patch, we fail earlier with exit code 1:
$ ./qemu-io -f qcow2 -c 'read -P 1 0 1024' file; echo $?
can't open device file: Image is not in qcow2 format
1
Failing earlier, we don't log this error now:
no file open, try 'help open'
But some tests expected it; the line was removed from the test output.
