src/osd/PG.h: use empty() instead of size()

Fix warning for usage of objects.size(). Use empty() since it
should be prefered as it has, following the standard, a constant
time complexity regardless of the containter type. The same is not
guaranteed for size().

warning from cppchecker was:
[osd/PG.h:599]: (performance) Possible inefficient checking for
  'objects' emptiness.
