    bhyveload: open guest boot disk image O_RDWR
    
    When a boot environment has been booted via the bootonce feature,
    userboot clears the bootonce value from an nvlist but fails to write the
    updated nvlist back to disk.
    
    The failure occurs because bhyveload opens the guest boot disk image
    O_RDONLY, fix this by opening it O_RDWR.
