ASoC: wm_adsp: Use vmemdup_user() instead of open-coding

Browse source

Use vmemdup_user() to get a copy of the user buffer in wm_coeff_tlv_put().

Apart from simplifying the code and avoiding open-coding, it means we
also automatically benefit from any security enhancements in the code
behind vmemdup_user().
