Subject: ALSA: firewire-tascam: Fix to handle error from initialization of stream data

From: Takashi Sakamoto <o-takashi@sakamocchi.jp>

commit 6a2a2f45560a9cb7bc49820883b042e44f83726c upstream.

This module has a bug not to return error code in a case that data
structure for transmitted packets fails to be initialized.

This commit fixes the bug.
