hyper-v: Tools: hv: Handle the case when the target file exists correctly

[Chris Valean]

Hello,
Please see the attached patch, it contains a fix for hv_fcopy_daemon file-copy tool which better handles the error reporting if a file already exists on the guest VM.
Would this be included in the final release or as a later update for 14.04?

Thank you!
Chris

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Hi Luis,
I've tried to use the -proposed branch, however it fails to find the new kernel.
