ASoC: topology: kfree kcontrol->private_value before freeing kcontrol
kcontrol->private_value is being kfree'd after kcontrol has been freed
(in previous call to snd_ctl_remove). Instead, fix this by kfreeing
the private_value before kcontrol.
CoverityScan CID#1388311 "Read from pointer after free"
Fixes: eea3dd4f1247a ("ASoC: topology: Only free TLV for volume mixers of a widget")
