Subject: [PATCH -next 3/4] ALSA: cs5535audio: Remove unused variable 'loop_count'

Reported by Clang [-Wunused-but-set-variable]

The variable 'loop_count' is introduced in this commit
'commit 719f82d3987a ("ALSA: Add support of AudioScience ASI boards")'

However, since introduced it had never been used.
Remove it for code cleaning
