ASoC: codecs: aw88399: Fix -Wuninitialized in aw_dev_set_vcalb()

Clang warns (or errors with CONFIG_WERROR=y):

  sound/soc/codecs/aw88399.c:441:18: error: variable 'vsense_select' is uninitialized when used here [-Werror,-Wuninitialized]
    441 |         vsense_select = vsense_select & (~AW88399_VDSEL_MASK);
        |                         ^~~~~~~~~~~~~
  sound/soc/codecs/aw88399.c:431:28: note: initialize the variable 'vsense_select' to silence this warning
    431 |         unsigned int vsense_select, vsense_value;
        |                                   ^
        |                                    = 0
  1 error generated.

This clearly should have been using the value received from
regmap_read(). Use the correct variable to resolve the warning.
