[Xen-changelog] Update comment/variable names to reflect the fact that the backend paths now

[Xen patchbot -unstable <patchbot-unstable@xxxxxxxxxxxxxxxxxxx>]

# HG changeset patch
# User emellor@ewan
# Node ID 034ada135379666b6c20b30788b206c2daa1af11
# Parent  4a2c162d3e7caf3016fd728f7b0a63b997d09427
Update comment/variable names to reflect the fact that the backend paths now
contain the frontend domid, not the uuid.  The actual functionality is the same,
because the ID is referred to by path level, so the change in semantics is not
a problem.
