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,

When PE passed to guest, and guest EEH occured with this PE,
EEH_PE_ISOLATED maybe set in host.
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.
