kcc: default to logging to DBGLVL_WARNING

kcc: default to logging to DBGLVL_WARNING

If the "-d" debug level parameter is not supplied, default to DBGLVL_WARNING.
Overiding the "log level" set in smb.conf.

When samba runs the kcc command stderr output is logged at DBGLVL_ERR,
the default log destination is stderr.  As a result any log messages
generated by the kcc command, are effectively logged at DBGLVL_ERR.
This causes issues if auth or audit logging are enabled in smb.conf.
