ASoC: wcd934x: Remove some unnecessary NULL checks

Browse Source 
Clang warns:

../sound/soc/codecs/wcd934x.c:1886:11: warning: address of array
'wcd->rx_chs' will always evaluate to 'true' [-Wpointer-bool-conversion]
        if (wcd->rx_chs) {
        ~~  ~~~~~^~~~~~
../sound/soc/codecs/wcd934x.c:1894:11: warning: address of array
'wcd->tx_chs' will always evaluate to 'true' [-Wpointer-bool-conversion]
        if (wcd->tx_chs) {
        ~~  ~~~~~^~~~~~
2 warnings generated.

Arrays that are in the middle of a struct are never NULL so they don't
need a check like this.
