Subject: [PATCH 5.5 137/189] ASoC: Intel: Skylake: Fix available clock counter incrementation

From: Amadeusz Sławiński <amadeuszx.slawinski@...ux.intel.com>

commit 8308a09e87d2cb51adb186dc7d5a5c1913fb0758 upstream.

Incrementation of avail_clk_cnt was incorrectly moved to error path. Put
it back to success path.

Fixes: 6ee927f2f01466 ('ASoC: Intel: Skylake: Fix NULL ptr dereference when unloading clk dev')
