-----------
IOSurfacePool should not mark inUse surfaces as volatile

rdar://167596824
Reviewed by Tim Horton.
It is incorrect to call setVolatile(true) on an IOSurface
whose contents are currently in use, as they could be immediately
purged by the system leaving in use contents undefined.
Note, in use surfaces are added to m_surfaceDetails in
IOSurfacePool::willAddSurface so before calling setVolatile(true),
check to see if the surface is no longer in use.
