ALSA: hda/ca0132: Fix using plain integer as NULL pointer in add_tuning_control

Browse Source 
The 'add_tuning_control' function initializes two pointers using the
integer 0 instead of the NULL pointer, triggering sparse warnings.
Replaced both instaces of '0' with 'NULL' to resolve the type mismatch
and suppress the sparse warnings.
