If the SetVirtualAddressMap() is not called, mIsVirtualAddrConverted
is FALSE and the kernel crash occurs in IsNestedFmpCapsule() when
executing gBS->LocateProtocol () in the else case.
To serve the omitted SetVirtualAddressMap() call, we could just check
mEsrtTable presence instead of relying on mIsVirtualAddrConverted.

Agreed: SetVirtualAddressMap() is optional, so whether it has been
called or not should not be used as a proxy to decide whether or not
we are still running in the boot services context.
