ALSA: pcsp - fix printk format warning again

The commit 5a641bcd6398841cc4606b0a732d41a09256fd94 changed the printk format to '%lu', but the value passed seems to be dependent on the architecture. On x86-64, I got a new warning now because an int value is passed actaully. As a workaround, just cast the value always to unsigned long. Signed-off-by: Takashi Iwai <tiwai@suse.de>
