gpio: htc-egpio: remove redundant error message

Browse Source 
There's no need to emit an error message on probe failure unless we're
printing some meaningful info. Otherwise the core driver code will
inform us about a probe error. Also: the driver currently drops info
about errors propagated from called functions by default to returning
-EINVAL. This fixes it as well.
