mds/CDentry.h: use projected.empty() instead of projected.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:
[src/mds/CDentry.h:234]: (performance) Possible inefficient
  checking for 'projected' emptiness.
