firmware: cs_dsp: Perform NULL check in cs_dsp_coeff_write/read_ctrl

Browse source

Add a NULL check to the cs_dsp_coeff_write/read_ctrl functions. This is
a major convenience for users of the cs_dsp library as it allows the call
to cs_dsp_get_ctl to be inlined with the call to read/write the control
itself.
