vxge: Modify __vxge_hw_device_is_privilaged() to not assume function-0 as the privileged function: Resubmit#1 

- vxge driver was assuming function-0 is always the privilaged function. Now that
  restriction has been removed any function can act as a privilaged function.

- This patch modifies the __vxge_hw_device_is_privilaged routine to not assume
  function-0 as the privileged function.

- Recreated the patch by incorporating review comments from Dave Miller to
  remove double slash in path names.
