ASoC: msm-lsm-client: Add poll_enable to snd_lsm_detection_params_32

Polling doesn't gets enabled even though poll_enable is set from
userspace. This is because, "poll_enable" is not
added in snd_lsm_detection_params_32 structure, resulting in
setting wrong value for "poll_enable"
Added "poll_enable" to snd_lsm_detection_params_32
