ALSA: hdspm - Fix jumping external wordclock frequency in AutoSync mode

When using Word Clock on RME MADI cards, AutoSync mode was alternating
betweeen MADI and WC due to a typo: AutoSync is indicated in the second
status register (status2), not the first one (status).

While the proc output was always correct, the reported WC frequency to
ALSA was unstable as mentioned in
