net: iosm: Prevent underflow in ipc_chnl_cfg_get()
The bounds check on "index" doesn't catch negative values. Using
ARRAY_SIZE() directly is more readable and more robust because it prevents
negative values for "index". Fortunately we only pass valid values to
ipc_chnl_cfg_get() so this patch does not affect runtime.
