ASoC: wm_adsp: Prevent negative string length in wm_adsp_control_add()
Check that avail does not become < 1 in wm_adsp_control_add(). This
prevents overflows during subsequent operations.
The main aim is to trap a negative value in avail, but a zero length
would mean that the control ends up without a name, so 1 is the smallest
valid value.
