    gpt(8): Clear errno before retrying open() in gpt_open()
    
    Otherwise, the stale errno would go through gpt_read() when it failed
    with a partial read, and the program would print a weird error message
    like:
    ```
    gpt show: unable to open device 'vn4': No such file or directory
    ```
