ASoC: wcd9xxx: Add check for NULL pointer and buffer overflow

Current code has possible scenarios where NULL pointer
could be dereferenced or an out-of-bound index of array
could be accessed. The change checks the pointer for NULL
before they are dereferenced and checks for buffer overflows
to ensure out of bound indexes of arrays are not
accessed.
