tools/firewire: nosy-dump: work around segfault in decode_fcp
If I run "nosy-dump --view=transaction" with my camcorder on battery instead of mains, it segfaults very quickly because of !t->request. Perhaps this is because of increased likelyhood of incomplete transactions (ack_busy when host writes to camcorder's FCP_Request) and a bug deeper in nosy-dump's transaction housekeeping. This is a quick workaround to get me going. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
