NetworkPkg/IScsiDxe: Set ExitBootServiceEvent to NULL after close it.
v2: * Refine the commit log. There are two place to close the ISCSI ExitBootServiceEvent: #1.IScsiOnExitBootService(), which is the callback function of ExitBootServiceEvent. #2.IScsiCleanDriverData(), which will be invoked by ISCSI driver binding stop(). So, the ExitBootServiceEvent will be closed and freed when exit boot server is triggered. But it may be closed and freed again in ISCSI driver binding stop(), which will result in the issue recorded at https://bugzilla.tianocore.org/show_bug.cgi?id=742. This patch is to resolve the issue.
