ASoC: codecs: Fix error code in aw88261_i2c_probe()

Passing zero to dev_err_probe is a success which is incorrect when
i2c_check_functionality() fails.

Fix this by passing -ENXIO instead of zero to dev_err_probe().

ASoC: codecs: aw88261: avoid uninitialized variable warning

aw88261_reg_update() returns an unintialized error code in the
success path:

sound/soc/codecs/aw88261.c:651:7: error: variable 'ret' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]
if (aw_dev->prof_cur != aw_dev->prof_index) {

sound/soc/codecs/aw88261.c:660:9: note: uninitialized use occurs here
return ret;

sound/soc/codecs/aw88261.c:651:3: note: remove the 'if' if its condition is always true
if (aw_dev->prof_cur != aw_dev->prof_index) {
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Return zero instead here.
