dsp: q6afe: Update lpass hw votes to maintain separate handles

Browse Source 
lpass client handle variable stores latest lpass hw vote.
During PDR, core hw vote release proceed to call unvote
for stale handle since above variable is set to non-zero
as part of audio hm vote. Maintain separate handles for
respective lpass hw votes inorder to fix this.
