Subject: [PATCH] GCC: do not pass unique_ptr to DCHECK_NE, but the actual pointer, in CompositorFrameReporter

DCHECK_NE comparison requires CheckOpValueStr to be defined for the
type, or providing an output stream operator. A unique_ptr does not
provide any.

Compilation in GCC is failing in CompositorFrameReporter because of
this:
../../cc/metrics/compositor_frame_reporter.cc: In member function ‘void cc::CompositorFrameReporter::ReportEventLatencyHistograms() const’:
../../base/check_op.h:224:59: error: no matching function for call to ‘CheckOpValueStr(const std::unique_ptr<cc::EventMetrics>&)’

Fixed comparing the result of get() method for unique_ptr instead of
the unique_ptr.

Bug: 819294
Change-Id: I11103d1867c7196c1de92e72f9f12dcfd31c29f1

(updated to use DCHECK as suggested in comments)
