[PATCH v2 3/3] pwm: stm32: Fix error message to not describe the previous error path

[Uwe Kleine-König]

"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.

Fixes: d44d635635a7 ("pwm: stm32: Fix for settings using period > UINT32_MAX")
