[PATCH 17/18] libxl: timeouts: Break out time_occurs

[Ian Jackson <ian.jackson@eu.citrix.com>]

From: Ian Jackson <Ian.Jackson@eu.citrix.com>

Bring together the two places where etime->func() is called into a new
function time_occurs.  For one call site this is pure code motion.
For the other the only semantic change is the introduction of a new
debugging message.
