pwm: stm32: Fix error message to not describe the previous error path

Browse Source

commit f01af3022d4a46362c5dda3d35dea939f3246d10 upstream.

"Failed to lock the clock" is an appropriate error message for
clk_rate_exclusive_get() failing, but not for the clock running too
fast for the driver's calculations.

Adapt the error message accordingly.
