libxl: suspend: New libxl__domain_pvcontrol_xspath
Factor out the pv control node xenstore path calculation into
libxl__domain_pvcontrol_xspath.
This xs path calculation was open coded in
libxl__domain_pvcontrol_read and _write. This is undesirable because
it duplicates the code and because it makes the path inaccessible to
other parts of libxl (which are soon going to want it).
No functional change.
