[PATCH] kernel32: Make GetFinalPathNameByHandle warn on mounted folder.

[Jeff Smith]

GetFinalPathNameByHandle attempts to translate a volume mount point to
an NT volume name using QueryDosDevice, but this can only succeed if the
mount point is a drive letter.  When GetVolumeNameForVolumeMountPoint
encounters a similiar situation, it emits a fixme message.

When attempting to translate a volume mount point to an NT volume name
with GetFinalPathNameByHandle, for a mount point that is not a drive
letter, emit a fixme message.
