Subject: rgw/rgw_gc.cc: use !empty() instead of size() to check for emptiness
X-Git-Tag: v0.58~66^2~35

rgw/rgw_gc.cc: use !empty() instead of size() to check for emptiness

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().
