Hi, all

After discussing with Gavin offline, it's inappropriate to drop ISOLATED state. Please ignore this patch.

Otherwise, somebody will merge that to mainline, which would be a problem.

Thanks,

It is a big issue when the PE  is reused by host, host EEH
will not work on this PE because it was set to EEH_PE_ISOLATED
unexpectly.
