This commit adds an initialisation for the `bias_dims` variable, which
is given as an input to the `arm_depthwise_conv_s8` function.
Note that the `bias_dims` parameter is currently unused by the function
implementation.
This fixes the following warning reported by the GCC 12:
error: 'bias_dims' may be used uninitialized
Werror=maybe-uninitialized]
