[libvirt] [PATCH] Fix minor details in apic eoi

[Martin Kletzander]

The introduction of APIC EOI patches had a few little details that
could look better, so this patch fixes that.

The fixes:
 - "on" and "off" as values are changed to <code>on</code> and
   <code>off</code> respectively, because the code around uses the
   same tags for such values.
 - VIR_FREE is unnecessary as it is done in the error handling as well
 - one empty line stayed in my local changes not included in the sent
   patch, the code around is separated in similar fashion
 - For const strings, virBufferAddLit should be used instead of
   virBufferAsprintf.
