This code was supposed to trigger a BUG() if we truncate the output but
it's off by one so it allows one character to be truncated.  Really
drivers shouldn't call BUG_ON() and especially for something minor like
this so I've changed it to a WARN_ON().

The current code returns success if prism2_init_local_data() fails, but
we want to return an error code.  Also we can remove the bogus
ret initializer because it is wrong and never used.
