[fpc-pascal] TProxyStream.Check always raises error.

[Virgo Pärna]

	Is there any reason, why TProxyStream.Check always raises
Exception without checking, if err = S_OK (ISteam call succeeded).
TOleStream overrides this Check to use OleCheck, which handles it. But
if Check needs to be overrided for it to be useful, shouldn't Check just
be abstract?
