ALSA: firewire-lib: fix wrong assignment for 'out_packet_without_header' tracepoint

commit aa9a9e39b4f65733bf19d90cbd026e85a74efb99 upstream.

An initial commit to add tracepoints for packets without CIP headers
introduces a wrong assignment to 'data_blocks' value of
'out_packet_without_header' tracepoint.

This commit fixes the bug.
