Subject: clk: clk-wm831x: fix a logic error

From: Pan Bian <bianpan2016@163.com>

commit 20979202ee6e4c68dab7bcf408787225a656d18e upstream.

Fix bug https://bugzilla.kernel.org/show_bug.cgi?id=188561. Function
wm831x_clkout_is_prepared() returns "true" when it fails to read
CLOCK_CONTROL_1. "true" means the device is already prepared. So
return "true" on the read failure seems improper.
