Invalid exception message in create_volume_from_image.

[Kiyohiro Adachi]

When the PowerVMFileTransferFailed occurs in
PowerVMLocalVolumeAdapter.create_volume_from_image, in some cases the
message is incorrect.

I think you should describe the details about 'in some cases the message is incorrect'.
How do you think?

[Kiyohiro Adachi (adachi)]

Sorry!
I thought when I found this problem to occur in the case of more than one.
But take a closer look when I want to create a patch, after all conditions was one.
It is when the following code failed.

        # Calculate file size in multiples of 512 bytes
        output = self.run_vios_command("ls -o %s|awk '{print $4}'" %
                                  final_path, check_exit_code=False)

Thank you for your comment.

    Fixes the usage of PowerVMFileTransferFailed class

    If it fails in the process of "Calculate file size in multiples of 512
    bytes", the exception.PowerVMFileTransferFailed message is illegal.
    "KeyError: u'file_path'" is occurs when there is no argument.
