ALSA: dice: fix regression for Lexicon I-ONIX FW810S



For Lexicon I-ONIX FW810S, the call of ioctl(2) with
SNDRV_PCM_IOCTL_HW_PARAMS can returns -ETIMEDOUT. This is a regression due
to the commit 41319eb5 ("ALSA: dice: wait just for
NOTIFY_CLOCK_ACCEPTED after GLOBAL_CLOCK_SELECT operation"). The device
does not emit NOTIFY_CLOCK_ACCEPTED notification when accepting
GLOBAL_CLOCK_SELECT operation with the same parameters as current ones.

This commit fixes the regression. When receiving no notification, return
-ETIMEDOUT as long as operating for any change.

Fixes: 41319eb5 ("ALSA: dice: wait just for NOTIFY_CLOCK_ACCEPTED after GLOBAL_CLOCK_SELECT operation")
