Subject: [PATCH] leds: pca9532: Remove irrelevant error message

The update_hw_blink() function prints an error message when hardware is
not able to handle a blink configuration on its own. IMHO, this isn't a
'real' error since the software fallback is used afterwards.

Remove the error messages to avoid flooding the logs with unnecessary
messages.
