ASoC: Intel: Skylake: Fix NULL ptr dereference when unloading clk dev

Browse source

When driver is probed, we iterate over NHLT and check if clk entries are
present. For each such entry we call register_skl_clk and keep the
result in data->clk[].
Currently data->clk is sparsely indexed using NHLT table iterator, while
when freeing we use number of registered entries. Let's just use
data->avail_clk_cnt as index, so it can be reset back in
unregister_src_clk.
