Fix wrong selection of tag match for receive context

According to "1394 OHCI" specification (the one as of Jan 6, 2000 I referred),
tag1 (shown as FW_ISO_CONTEXT_MATCH_TAG1 in code) is the tag which matches to
the tag in isochronous packet header for CIP (0x01, shown as TAG_CIP in code).
The tag1 should be applied but tag2 was applied because of my misunderstanding
the value for CIP tag. I misunderstood it as 0x02.

If wrong match tag is applied, the code cannot receive callback from juju and
cannot handling Isochronous receive stream for CIP. This means we cannot deal
with PCM/MIDI capture.
