Subject: [PATCH] conffile: don't report error from conf_init_file()

conf_init_file() currently reports an error if the main config file
doesn't exist - even if there are conf files in the conf.d directory.

This is only used by nfsconfcli.c.  However this is not needed.  If
there is a real error, and error message is already logged.
If it is simply that the file doesn't exist, that isn't really an error.

So remove the error messages and change conf_init_file() to not return
any status.

Also fix up assorted nearby white-space issues.
