Reviewed by Chris Dumez.

In ResourceMonitor.cpp, a macro to produce RELEASE_LOG is defined and m_frame weak ptr is used without checking.

Add check before calling that macro.

(WebCore::ResourceMonitor::setEligibility):
(WebCore::ResourceMonitor::addNetworkUsage):
(WebCore::ResourceMonitor::updateNetworkUsageThreshold):
* Source/WebCore/loader/ResourceMonitorChecker.cpp:
