ASoC: msm: qdsp6v2: fix crash issue on playback

Crash is observed on playback in adm open while checking for set
bit. Enumerator takes the size sufficient enough to hold the values
and the set_bit api expects unsigned long and manipulates bits. So
when we pass enum type of variable it crashes. Changing it to
unsigned long fixes the issue.
