ASoC: msm: qdsp6v2: fix to remove ftm_cfg mode update

Speaker FTM(factory test mode) configuration mode is reset
during afe_set_cal_fb_spkr_prot() API which is causing FTM
mode to be overwritten if afe_set_cal_fb_spkr_prot() API
is called before FTM mode sent to DSP. Fix this issue by
not resetting FTM mode.
